These pictures from the Syrian frontline show the reality of the fight Britain could join later today.

An unexploded suicide vest lies on the ground next to the bodies of ISIS militants in stark images from theSyrian town of Ain Issa.

Other pictures show the ruins of buildings pounded by airstrikes along the frontline of the battle between ISIS and Syrian Kurds.

British fighter jets have returned from their first airstikes against ISIS in the terror group's Syria stronghold, the Ministry of Defence confirmed in the early hours of Thursday.

Two Tornado jets were deployed from RAF Akrotiri, Cyprus, to bomb ISIS in Syria just 57 minutes after MPs voted in favour of military action by 397 votes to 223 - a majority of 174.

A further two Tornados took off from the base hours later.

Ain Issa has already been a target for forces already involved in air strikes in the country.

In the last 24 hours alone, US bombers have carried out two strikes which hit a tactical unit and took out two ISIS fighting positions.

Pictures taken by ITV show buildings smashed to pieces and a Sharia Court building abandoned by ISIS in Al Hawl.

Last night, David Cameron boasted Britain is 'safer' after the House of Commons vote. Some 66 of Labour MPs defied their pacifist leader Jeremy Corbyn to back the Tory government, after Mr Cameron warned Britain had to strike at the heart of ISIS or 'wait for them to attack us'.

Within hours of the vote, two more Tornado GR4 jets and a Voyager refuelling tanker took off from RAF Marham, Norfolk for the region.

Six Typhoon jets will also deploy from RAF Lossiemouth, Scotland, doubling the number of attack aircraft at the British base.

Just half an hour before the vote, Mr Corbyn sat stony-faced as his shadow foreign secretary Hilary Benn was cheered in the Commons for a stirring speech in which he declared: 'We must now confront this evil.'

The stirring speech is thought to have swayed wavering Labour MPs, helping the government to a majority much higher than the predicted 100. The Lib Dems and DUP backed the airstrikes, while the Scottish National Party claimed the government had not made the case for war.

Ex-Paratrooper and Labour MP Dan Jarvis said ISIS are the 'fascists of our time' as he urged MPs to unite with Britain's allies 'in defence of our common humanity'.

Labour leader Jeremy Corbyn accused the government of rushing into the vote before 'before it slips from his hands', as a poll showed public support for airstrikes was falling.

Former Labour leader Ed Miliband and ex-Tory leadership contender David Davis confirmed they would oppose military action.
