LONDON - British Prime Minister David Cameron said on Tuesday he will set out a comprehensive strategy for tackling Islamic State militants, including why he believes the country should join international airstrikes against the group in Syria.

"I will set out our comprehensive strategy for dealing with ISIL (Islamic State), our vision for a more stable and peaceful Middle East. This strategy, in my view should include taking the action in Syria I've spoken about," Cameron told parliament.

"Our allies are asking us to do this, and the case for doing so has only grown stronger after the Paris attacks."
