LONDON, April 11 (Reuters) - British Prime Minister Theresa May has ordered British submarines to move within missile range of Syria in readiness for strikes against the Syrian military that could begin as early as Thursday night, the Daily Telegraph newspaper said.

May has not reached a final decision on whether Britain would join any strikes by the United States and France in response to a suspected chemical attack, but wants to be able to act swiftly, the newspaper said.

It quoted government sources as saying Britain was “doing everything necessary” to be able to fire Tomahawk cruise missiles from submarines against military targets in Syria. (Writing by William Schomberg Editing by Robin Pomeroy)
