Foreign ministers from around the world converged at a summit in Paris to discuss a global response to the threat posed by militants for the Islamic State of Iraq and Syria (ISIS).
Speaking at the summit, French President François Hollande (left) said their was "no time to lose" in international efforts against ISIS.
U.S. officials speaking at the summit revealed that several Arab countries had agreed to assist them in airstrikes against ISIS in Iraq, the BBC reported.
One country that won't be cooperating with U.S. action is Iran. The country's supreme leader, Ayatollah Khamenei, tweeted that Iran rejected an offer to cooperate against ISIS because the U.S. had itself been involved in "creating and spreading" terrorism. He said the U.S. planned to use the battle against ISIS to "dominate the region."
