Newspaper headlines: Syria strikes approved, Labour divisions and 'what next?'

Parliament's decision to approve air strikes against so-called Islamic State (IS) in Syria dominates the front pages.

David Cameron won "huge backing" for the strikes after a House of Commons debate which lasted more than 10 hours, the Times reports, external. It says the victory - by 397 votes to 223 - was "bigger than most had predicted".

In a comment piece, the paper says, external MPs were right to approve air strikes, but it is "not reasonable" to expect the IS stronghold of Raqqa to fall without troops on the ground.

Writing in the Daily Express, Col Richard Kemp supports air strikes and says Britain must fight IS "relentlessly". He says bombing will provoke IS attacks in the UK, but adds: "They are trying to kill us anyway".

The Daily Mirror accuses Mr Cameron of a "rush to war", saying questions about holes in his long-term strategy have not been answered.

The Daily Mail says, external UK jets were ready to cross the border from Iraq - where bombing raids are ongoing - to Syria "within minutes" of Parliament's vote.

During the Commons debate Mr Cameron refused - nine times - to apologise for earlier urging his MPs not to vote with "Jeremy Corbyn and a bunch of terrorist sympathisers", the Guardian reports.

But the Sun says the "Marxist dimwits" leading Labour deserved no apology.

"You won't catch me with terror sympathisers" proclaims a cartoon of Mr Cameron in the Times, external, which depicts him alongside Vladimir Putin and Bashar al-Assad, presidents of Russia and Syria.

John Crace, writing in the Guardian, external, says both Mr Cameron and Mr Corbyn seemed confused and performed poorly in the Commons. But, he adds, "almost every mind had been made up" before the debate started.

The voting plans of Labour MPs have made headlines in recent days, and the Telegraph says, external shadow foreign secretary Hilary Benn "spearheaded a show of defiance" against Mr Corbyn. It says Mr Benn was cheered by Labour and Conservative MPs after a "rousing speech" in favour of air strikes.

In the Times, external, Patrick Kidd says the best pro-bombing speeches came from Labour backbenchers, while the strongest arguments against the government's plan came from "reluctant" Tories.

Several papers, including the Daily Star, say pro-bombing Labour MPs faced intimidation from anti-war activists - with some receiving pictures of dead children.

The Independent says, external Mr Corbyn has come under fire from his own party for "failing to take a hard line" against those handing out abuse.

In a stinging attack on the Labour leader, the Telegraph says, external he "cannot be trusted with the security of the British people".

While many papers focus on the Commons vote and RAF bombing, the Daily Mail looks further ahead and asks, external: "What comes next?"

It quotes former Foreign Secretary William Hague, who says the UK "should not rule out... the use of perhaps small specialist ground forces from Western nations".

In a comment piece, the Mail criticises, external Mr Cameron's "all-too-vague war aims" and says there are "uncomfortable echoes of Tony Blair, dodgy dossiers and the Iraq fiasco in the prime minister's evasiveness".

It says an "army of occupation" - including troops from Arab states - will be needed.

One difficulty of the bombing campaign is highlighted in the Times, which says civilians have been banned from leaving Raqqa by IS because "their presence acts as a human shield". Militants have stopped travelling in convoys and witnesses suggest they are digging deep tunnel systems, the paper adds.

A mass shooting at a centre for the disabled in San Bernardino, California, left at least 14 people dead, the Times reports, external.

It says three gunmen in body armour opened fire during a staff Christmas party at the centre, before fleeing in a vehicle.

The Express says, external it is the latest in a spate mass shootings in the US where, as the paper puts it, "debate continues to rage over gun control".

One in five Britons has finished a packet of biscuits in one sitting, according to a survey reported in the Daily Express.

Despite "growing obesity concerns", the paper says, a third of adults regularly eat four or more biscuits in one sitting - most often with a cup of tea.

Speaking of less-than-ideal lifestyle habits, the Telegraph reports, external on a study which suggests watching too much TV and not getting enough exercise in early adulthood can damage long-term intelligence.

But not watching enough TV (and films) may also have its pitfalls, as a Turkish judge has discovered, according to the Guardian, external.

It says Turkish media reports suggest the trial of a man accused of insulting the country's president has been stopped as the chief judge has not seen the Lord of the Rings films.

The court needs to establish whether likening President Recep Tayyip Erdogan to Gollum insulted him, the paper explains.
