Britain's top military commander has warned the UK is "letting down" its allies by not taking part in airstrikes against so-called Islamic State in Syria.

Chief of the Defence Staff, General Sir Nicholas Houghton, compared the situation to being asked to win a football match without going into the opponents' half.
