As we reported earlier, Home Minister Amit Shah has held a number of meetings today with senior officials. He has just posted on X that he has "instructed them to hunt down each and every culprit behind this incident".

"Everyone involved in this act will face the full wrath of our agencies," he added.

Shah is the third senior Indian minister today - after PM Narendra Modi and Defence Minister Rajnath Singh - to say that those responsible for the explosion will be brought to justice.

The Delhi police have also registered a case under the anti-terror law though they haven't given a reason for it.

So, there is no clarity yet on what caused the blast and who, if anyone, is behind it.

Authorities say eight people were killed in the blast, while 20 others were injured. An update is expected later today.

Six of those whose bodies have been identified are:

• Lokesh Agrawal, a shop-owner from the neighbouring Uttar Pradesh state, who was visiting a relative at a hospital in the capital
• Ashok Kumar, a bus conductor who worked for the government-run Delhi Transport Corporation and was returning home after duty

• Pankaj Sahni, a 22-year-old taxi driver, whose family told the Press Trust of India that his car was blown to pieces in the blast
• Amar Kataria, a 34-year-old businessman, who was on his way to take the metro
• Mohsin, an e-rickshaw driver from Meerut city, who had come to Delhi to look for work, his family told IANS news agency
• Nouman, a 22-year-old cosmetics shop-owner from Shamli in Uttar Pradesh, who was in Delhi to buy supplies. His cousin Aman, who accompanied him, was injured in the blast, their family told IANS

Several others are searching for their missing relatives and waiting to get more information on what happened to them.

Chinese Ambassador to India Xu Feihong extended his condolences to the families of the victims of the Delhi blast.

"Saddened by the explosion near Delhi’s Red Fort metro station. My deepest condolences to the victims and my thoughts are with everyone affected," he said in a post on X.

Sri Lanka, the Maldives and Nepal have offered condolences to India following the blast.

Sri Lankan President Anura Kumara Dissanayake said he was “saddened by the news of the explosion".

"Sri Lanka stands in solidarity with the people of India. Our thoughts are with all those affected," he wrote in a post on X.

Maldives President Mohamed Muizzu said he was “deeply saddened by the tragic loss of lives".

“Our heartfelt condolences to the bereaved families and good wishes for swift recovery of the injured," Muizzu wrote on X.

Nepal’s interim Prime Minister Sushila Karki also expressed her “deepest condolences to the bereaved families and prayers for the speedy recovery of the injured".

India's main opposition Congress party has urged the government to clarify "whether it was an attack or something else".

Eighteen hours after the incident, there is still no clarity from "the government, home ministry, Delhi police", party spokesperson Pawan Khera says.

"There is fear and concern among the people that such a thing happened in the country's capital, so it is important to have answers," he told Press Trust of India.

A water seller injured in Monday’s blast told the Press Trust of India that he was lucky to have survived.

“I was setting up my water cart and was about 10 steps away from Red Fort metro station when the blast took place,“ he told the news agency.

“I was knocked unconscious and didn’t know what hit me. When I got up again, the administration arrived and made everyone leave,” he said. “We left all our belongings scattered there at the site."

The man said he was wounded on his forehead and chin and had a deep cut on his right forearm. He said he went to a private hospital for initial treatment and had returned to the area to seek proper treatment at Lok Nayak Hospital.

Indian news agencies are reporting that Home Minister Amit Shah has briefed President Droupadi Murmu about the Red Fort blast.

The president, who is currently on a state visit to the central African nation of Angola, spoke to Shah over the phone from there.

Earlier, President Murmu expressed her condolences over the loss of lives and prayed for the swift recovery of those injured in a social media post, external.

Indian Home Minister Amit Shah has been holding a series of meetings since early this morning.

A short while ago, he arrived at the home ministry office in Delhi to chair a second round of security reviews, news agency ANI reported.

He chaired a high-level security meeting earlier today following the deadly blast near the Red Fort that killed eight people, but details of what was discussed have not yet been released.

Meanwhile, several Indian ministers - including Prime Minister Modi - have said that those responsible for the blast “will be brought to justice”.

There is still no confirmation of what led to the blast.

Outside the Lok Nayak Hospital, where the injured were taken, the BBC’s Vikas Pandey spoke to Mohammed Azghar who hadn't heard from his brother since the blast. Mr Azghar said he was desperate for any news, whether “good or bad”. Sometime back, we checked with him again for any updates - he said he was still waiting.

Jigme Khesar Namgyel Wangchuck, the King of Bhutan, has led thousands of people in a prayer for the victims of the Delhi blast at the Changlimithang Stadium in Thimphu on Tuesday, news agency ANI reports.

A Global Peace Prayer Festival is being held at the stadium along with celebrations for the 70th birthday of Jigme Singye Wangchuck, the former king of Bhutan.

Prime Minister Narenadra Modi is in Bhutan on a two-day visit to attend these events.

"We would like to take a moment and pray for the people who sadly lost their lives in Delhi. We'd like to pray for them," the king said.

"Let us all come together and pray for India, pray for Prime Minister Modi," he added. "May all your aspirations, your vision and your service to India bear fruit. May you overcome each and every single obstacle. And may your dream of an even brighter, stronger, more prosperous India be fulfilled."

Soon after his arrival, Modi addressed the crowd at the Changlimithang Stadium where he said perpetrators of Monday's blast would be brought to justice.

There is still no official confirmation of what caused the blast.

On a normal day, the area outside the Red Fort would be crowded with shops and markets buzzing and tourists queuing up. But today it is deserted, except for the media teams and the police.

The debris and charred vehicles from Monday's explosion have now been covered up and security forces continue to patrol the area.

Investigators are still combing through the wreckage for evidence to determine the exact cause.

I saw a team of National Security Guards, which is India’s counter-terrorism force, entering the site of the incident.

A short while ago, we heard from Prime Minister Narendra Modi, who is in Bhutan on a two-day visit.

In his first public remarks since the explosion, Modi said the conspirators behind it “will not be spared”.

During the speech he briefly switched from Hindi to English and said that “all those responsible will be brought to justice”.

"I was in touch with all the agencies investigating this incident throughout last night. Our agencies will get to the bottom of this conspiracy," he said.

There is, however, still no official word on what led to last night's blast.

Sonu Agrawal says his older brother Lokesh died in Monday's blast while on his way back from visiting a relative at a hospital in Delhi.

Lokesh, father of two sons and a daughter, owned a shop in Amroha city in the neighbouring Uttar Pradesh state, his brother told news agency ANI.

"He had gone to Delhi to meet his son's mother-in-law, who is in hospital there. Afterwards, he was near the Red Fort metro station when the blast took place," Sonu Agrawal said.

"When we called his phone, a policeman picked up and informed us about the incident," he said.

Mr Agrawal said he also got a call later from the police since his was the last number Lokesh had dialled.

One of the people who have died in the blast is a bus conductor named Ashok Kumar who worked for the government-run Delhi Transport Corporation, his brother has told the IANS news agency.

“Ashok was going home after completing his duty,” Devendra Kumar said. “He lived in a room he had taken on rent.”

Devendra Kumar says his brother’s details are on the official list of the eight people who have died in Monday's blast.

“Ashok was 26-27 years old and has three children - two daughters and one son,” he adds.

Police say they are in the process of identifying all those who have died in last night's blast.

"We have identified six bodies and post-mortem has been done on five," official Raja Banthia told reporters on Tuesday. "The injured are getting treatment."

Indian Defence Minister Rajnath Singh has said the country’s top investigation agencies are probing the explosion that killed at least eight people in Delhi on Monday.

“The findings of the investigation will soon be made public”, he said, and assured that “those responsible for this tragedy will be brought to justice and will not be spared under any circumstances”.

A reminder here - there is still no official confirmation of what caused the blast.

Home Minister Amit Shah and other officials have said they are "exploring all possibilities".
