A total of 66 Labour MP's sided with the government as Mr Cameron secured a larger than expected Commons majority. MP's voted by 397 votes to 223 for UK action in Syria after a 10-hour Commons debate. Welcoming the Commons result, Foreign Secretary Philip Hammond said Britain was "safer because of the actions taken by MP's today".

Four Tornados took off from RAF Akrotiri in Cyprus shortly after MP's voted to approve bombing.
The strikes focused on six targets in an oil field under IS control in eastern Syria.
Two of the four jets have now returned to base. The Ministry of Defense confirmed they had carried out the "first offensive operation in Syria".

The first pair of Tornados had left RAF Akrotiri with three 500lb Paveway bombs each, and returned to base shortly before 03:00 GMT without those weapons. The jets used their Raptor pods - special long-range photography equipment - for surveillance, before dropping the Paveway bombs, our correspondent understands. An RAF Reaper unmanned drone was also in the air to provide intelligence sources mention.

The first pair of Tornados took off from RAF Akrotiri just over an hour after MPs authorised military action against Islamic State targets in Syria.Less than an hour later, they were followed by a second pair loaded with the same weapons. The Ministry of Defence has not given any details about their mission, but has confirmed these were the first British jets to carry out air strikes over Syria.

The use of bombs rather than the Brimstone missile suggests they were hitting static rather than moving targets - possibly infrastructure.

The relatively short mission suggests the Tornados had already been given specific targets before they left.
