The Israel Defense Forces (IDF) has just released a statement saying a Hezbollah leader was killed in a strike in Beirut on Sunday.
"The IDF now confirms that in a precise strike in Beirut last night (Sunday), the terrorist Hussein Makled, who served as the head of Hezbollah’s intelligence headquarters, has been eliminated," the statement reads.

The US-Israel attack on Iran has turned into a wider conflict, a fear that regional powers had shared as President Trump deployed what he described as an “armada” to the Middle East.
Iran has responded by attacking Israel and other countries. Now, Lebanon is being dragged into it too, after Hezbollah launched rockets and drones at Israel to avenge the killing of Supreme Leader Ayatollah Ali Khamenei.
For opponents, Hezbollah’s actions will be seen as reckless. And it is possible that even some supporters will be critical, fearing further domestic isolation and destruction.
Israel said it had launched an “offensive” campaign against the group, warning Israelis to “prepare for many prolonged days of combat”.
For months, there has been speculation that Israel could expand its attacks amid claims Hezbollah was attempting to rebuild its capabilities. It appears that time may have come.
Khamenei led a repressive regime for almost four decades and many are happy to see him dead. But neither Trump nor Netanyahu have laid out a clear justification for the attacks, as there was no known imminent threat from Iran, or explained what they are trying to achieve.
A fourth US service member who was wounded during Iran's initial attacks has "succumbed to their injuries", the US Central Command says.
Apparent Iranian strikes have been reported across the region. The US does not say where the attack in which this service member was injured took place.

Gas prices have risen sharply on international markets in response to the tensions in the Middle East.
In the UK just after midday, natural gas for delivery in April was trading up 42%, at just over 112p per therm.
Qatar is a major exporter of liquefied natural gas, accounting for about a fifth of global supplies – and most of this is transported by sea through the Strait of Hormuz.
While Qatar’s main customers are in South and East Asia, any interruption to the trade is likely to lead to price increases on global markets, because it increases competition for shipments coming from elsewhere.
The situation has been exacerbated by the closure of some gas-producing facilities in Israel as a security precaution.
Analysts say this could represent a serious problem for Europe, as although winter is coming to an end and consumption is slowing down, the region’s gas stocks are running low and will need to be refilled over the summer.
Qatar's state-owned energy company, QatarEnergy, says it has halted the production of liquefied natural gas (LNG) after Iranian attacks on some of its facilities.
It says the attacked facilities were Ras Laffan - an onshore gas processing base - and Mesaieed - another key site for Qatar's natural gas production.
The Gulf state is one of the world's top liquefied natural gas producers, alongside the US, Australia and Russia.
The Israel Defense Forces (IDF) has issued an "urgent" evacuation warning for buildings in the south of Beirut, Lebanon.
Arabic spokesperson Avichai Adraee says the military will soon strike infrastructure which is says belongs to the Hezbollah-linked group Al-Qard Al-Hassan Association (AQAH).
"You must evacuate immediately," he warns.
Israel says AQAH finances Hezbollah’s military activities - something the group denies. AQAH says it only provides small, interest-free loans to ordinary Lebanese.

I’ve just heard from a 38-year-old business owner who fled from his home in southern Lebanon today.
“I woke up to a phone call from my friend shouting ‘get up, get up - pack your bags. Rockets were fired from Lebanon,'” he says.
“Soon after, we heard the [Israeli] strikes hitting… we could hear the bombardment around us.”
The man, who asked not to be named because of fears for his safety, said he tried to return to sleep but got calls through the night from friends telling him to leave.
“I decided I would leave in the morning - in daylight, not at night. I didn’t want to drive in the chaos, in the traffic, in the dark.”
He says he “packed as many essential things as I could, put them in a car and left - my mother, my sister and me".
The Lebanese health ministry says Israeli attacks in Beirut and southern Lebanon have killed at least 31 people, with 149 injured.

The entry of Hezbollah in the conflict threatens to reopen a devastating year-long war between Israel and the Lebanese group which ended in a ceasefire 15 months ago.
Hezbollah – a Shia Islamist organisation – is one of the most powerful of the armed groups across the region which are loyal to Iran. The Islamic republic has spent billions of dollars funding, training and equipping it to oppose Israel for decades.
Hezbollah and Israel have repeatedly attacked one another since the group was formed in the 1980s. They fought a deadly war in 2006, and again in 2023-24, triggered by Hezbollah rocketing Israeli positions in support of Palestinians a day after Hamas’s deadly attack on Israel on 7 October and the start of Israel’s military campaign in Gaza.
During the last war with Hezbollah, Israeli attacks killed about 4,000 people in Lebanon and left more than 1.2 million displaced, Lebanon said. Israeli authorities said more than 80 of its soldiers and 47 of its civilians were killed.
Hezbollah was significantly weakened in the war and its firepower degraded. As part of the November 2024 ceasefire agreement, it agreed to withdraw extensively from southern Lebanon, although Israel has continued to attack Hezbollah targets which it says pose a threat.
The group’s rocket and drone attack on Monday and the Israeli response puts the ceasefire in jeopardy, leaving the populations of Lebanon and northern Israel anxiously wondering if the renewed hostilities will be limited or spiral once again into all-out war.

The Lebanese government has banned Hezbollah’s armed activities throughout the country, the prime minister said.
The decision marks one of the clearest challenges yet to the movement’s long-standing parallel authority.
The move follows Hezbollah’s rocket launches toward Israel on Monday, carried out without state consultation, which directly undercut the government’s declared policy of avoiding regional escalation.
Both President Joseph Aoun and Prime Minister Nawaf Salam framed the action as a violation of Lebanese sovereignty, warning it risked dragging the country into a broader war and providing Israel justification for retaliation.
How this plays out practically is still unclear as Hezbollah remains armed despite recent conflict with Israel.

Image source, ReutersAccess to those in Iran is difficult in the best of times. International news organisations are often refused visas, which severely limits their ability to gather information there.
From afar, what I'm hearing today about the current situation on the ground from two sources is that there is a heavy security presence on the streets during the night in Tehran and a nearby city, Karaj.
One person tells me prices have increased since the start of escalations and streets are mostly empty.
People are also angry about the current internet outage - which according to internet monitoring group NetBlocks has been ongoing for more than 48 hours.
Although streets are quiet, bakeries and petrol stations are busy.
Meanwhile, the Israel Defense Forces says it has received reports that a hospital in Tehran has sustained "minor collateral damage" following an attack on Sunday on nearby military infrastructure.
It says the hospital was not the target of the attack.

As we just reported, sirens have sounded at the UK base in southern Cyprus.
Now, a Cypriot government spokesperson says two drones heading towards RAF Akrotiri have been intercepted.
This comes after an Iranian drone crashed into the UK military base last night, "causing minor material damage".

Sirens are sounding again in Akrotiri, according to local reports, and British fighter jets have taken off.
A message sent to employees warned of an "ongoing security threat" and urged people to return home and remain indoors until further notice.
"Stay away from windows and take shelter behind or under sturdy, solid furniture. Please await further instructions," the alert said.
According to information received, the Cypriot interior minister has instructed the mayor of Kourion, near the UK base, to proceed with a mandatory evacuation.
Meanwhile, Cypriot media reports that an alarm was raised at Paphos Airport after a suspected drone was detected in its airspace.
Earlier, the Kuwaiti military said "several" US fighter planes had crashed in Kuwait - and that the circumstances of the incident were under investigation.
US Central Command has just now said three of its F-15 jets "flying in support of Operation Epic Fury" - the US operation against Iran - "went down over Kuwait due to an apparent friendly fire incident".
All six crew ejected safely and have been recovered, it says.
Footage verified by the BBC earlier shows the apparent moment a fighter jet was downed near Kuwait City - watch it below:

In a new update, the Israel Defense Forces (IDF) says it has "begun an additional broad strike" on the Iranian capital, Tehran.
This is targeting what it describes as "Iranian terror regime targets".
Conflict spreads to Lebanon
Apparent Iranian strikes around the region continue
Latest between Iran, the US and Israel
Meanwhile, in Cyprus
Iran's actions in the region represent a "dangerous escalation", which threatens stability in the Middle East, a joint statement from the US and six allied Gulf states says.
"Targeting civilians and non-combatant states is reckless behaviour that undermines stability," the statement - shared by Kuwait's foreign ministry - reads.
The statement - published originally in Arabic - was issued jointly by Kuwait, Saudi Arabia, Bahrain, Qatar, Jordan, the UAE and the US.
They say they "reaffirm our right to self-defence" as apparent Iranian strikes around the region continue.
It says attacks have taken place in Bahrain, Iraq (including the Kurdistan Region of Iraq), Jordan, Kuwait, Oman, Qatar, the Kingdom of Saudi Arabia, and the United Arab Emirates.
In a new statement, the Israel Defense Forces (IDF) says it's killed Sayed Yahya Hamidi, Iran's deputy minister of intelligence for Israel affairs.
Jalal Pour Hossein, head of the espionage division at the ministry of intelligence, was also killed, along with other "regime officials", it says.
It does not detail how, when or where they were killed.
It also adds that Iran's ministry of intelligence headquarters in Tehran was struck "a short while ago".
Saudia Arabia's energy ministry says a "limited fire" at the Ras Tanura refinery - which is run by the country's state oil company, Aramco - has been brought under control.
The statement - shared by the Saudi Press Agency - says the refinery sustained "minor damage from falling debris" due to the interception of "two drones in the refinery's vicinity". It adds that the fire was "immediately dealt with" by emergency services, with no injuries or fatalities.
Video verified by the BBC shows a fire and large plumes of smoke billowing from the refinery.
Saudia Arabia has long hosted US and western military forces, and on Saturday its government issued a statement condemning "blatant and cowardly Iranian attacks".
These attacks were "successfully intercepted" and targeted the Riyadh Region and Eastern Province, Saudi Arabia said.

Based on screenshots of two messages sent from inside Iran to the BBC, Iranians have been warned by the intelligence unit of the Islamic Revolutionary Guard Corps (IRGC) not to go out onto the streets to protest.
The messages describe any upcoming protests as “street riots” that are “planned by the enemy”, and warn that “any movement that disrupts security is considered an example of direct cooperation with the enemy".
In another text message, the IRGC has asked citizens to report “anti-security” incidents by calling them.
Since the death of Ayatollah Ali Khamenei, the BBC has verified videos from several cities showing gatherings of celebration in the streets.
At the same time, Iranian outlets have reported on groups of mourners in Tehran and other cities.
Meanwhile, the internet is still down for most people in Iran, so it’s very difficult to see a clear picture of what is going on inside, while some are able to connect through methods such as the satellite internet service, Starlink.
