U.S. Secretary of State John Kerry has called for a broad global coalition to combat Islamic State militants, also known as ISIS.
In an article published in The New York Times Saturday, Kerry said the terrorist group is a rising threat, not just in Iraq and Syria, but anywhere they could manage to travel undetected - including the United States.
He said ISIS fighters have exhibited repulsive savagery and cruelty, but could be checked with a united response of the "broadest possible coalition of nations" led by the United States.
President Barack Obama has said that he currently has no strategy to tackle the Islamic State group, but Kerry said in his newspaper piece that Washington will put forward an action plan at a summit of the U.N. Security Council in September during the General Assembly session.
Kerry ended the piece by saying, "Extremists are defeated only when responsible nations and their people unite to oppose them."
