UNITED NATIONS (AP) — With President Barack Obama presiding, the U.N. Security Council has unanimously adopted a resolution aimed at limiting the flow of fighters to terror groups like the Islamic State.

The resolution requires all countries to prevent the recruitment and transport of those fighters.

Obama earlier told the General Assembly that the task of rejecting extremism is “for the people of the Middle East themselves.” He said, “No external power can bring about a transformation of hearts and minds.”

Obama’s address came against the backdrop of an expanded U.S. military campaign against the Islamic State group, with airstrikes now hitting targets in both Iraq and Syria. A coalition of five Arab nations joined the U.S. this week in the strikes in Syria.
