NATO's secretary-general says he hopes for a decision by the time member countries' leaders meet May 25 on whether the alliance formally becomes a member of the coalition fighting the Islamic State group.

Jens Stoltenberg stressed after meeting German Chancellor Angela Merkel on Thursday that any such move wouldn't change NATO's fundamental role in the fight against IS.

He said that "NATO will continue to provide support, we will continue to focus on training. NATO will not be engaged in the combat operations."

The U.S. under President Donald Trump is keen for a greater emphasis on NATO fighting terrorism.

Members of the 28-nation alliance are part of the anti-IS coalition. NATO itself formally isn't, though it provides support with AWACS surveillance planes and with training in Iraq.
