Here is a look at the main developments Tuesday in the U.S.-led coalition’s campaign against militants from the Islamic State group.

— Warplanes from the U.S. and Arab allies strike Islamic State group positions in Syria for the first time, hitting training camps and other facilities. Saudi Arabia, Bahrain, the United Arab Emirates and Jordan confirm they participated in the strikes. Qatar played a supporting role. Among the targets hit was a government building used by the militants as a headquarters in their de facto capital, the Syrian city of Raqqa.
