Islamic State crisis: Obama threatens action in Syria
US President Barack Obama says he will not hesitate to take action against Islamic State (IS) militants in Syria as well as Iraq, the BBC reported.
In a nationally televised speech outlining his strategy against IS, he said that any group that threatened America would "find no safe heaven."
He also announced that 475 US military personnel would be sent to Iraq but said they would not have a combat role.
IS controls large parts of Syria and Iraq after a rapid military advance.
Its fighters have become notorious for their brutality, beheading enemy soldiers and Western journalists on video.
