UNITED NATIONS, Sept. 24 -- U.S. President Barack Obama on Wednesday urged all states to take "concrete" actions against terrorism, after United Nations Security Council adopted a resolution aimed at tackling foreign terrorist fighters.

"Resolutions alone will not be enough," Obama said at a special meeting of the UN Security Council. "The words spoken here today must be matched and translated into action, into deeds -- concrete action."

The 15-member UN Security Council on Wednesday unanimously adopted a U.S.-proposed binding resolution that requires all states to "prevent and suppress" the recruitment and travel of militant fighters in foreign conflicts.

"I'm here today to say that all of you who are committed to this urgent work will find a strong and steady partner in the United States of America," said Obama, who presided over Wednesday 's meeting.

The resolution is also a part of Obama's push for international action to destroy the Islamic State (IS) extremists who have taken over large swaths of Iraq and Syria.

Preventing foreign fighters from reaching Syria and then slipping back across U.S. borders is a critical element of the strategy to "degrade and ultimately destroy" IS, also known as ISIS or ISIL, said Obama.

"The historic resolution that we just adopted enshrines our commitment to meet this challenge," he added.
