Eight senior figures from Islamic State were killed in an air strike while meeting in a town in western Iraq, but the group's reclusive leader Abu Bakr al-Baghdadi did not appear to be among them, residents of the town and hospital sources said.

A year after Islamic State declared a caliphate on territory seized in Iraq and Syria, the al Qaeda splinter group faces military pressure from a U.S.-led coalition but remains a potent force holding key cities, the Pentagon said on Monday.

Fighters loyal to Islamic State have seized substantial territory in Afghanistan for the first time, witnesses and officials said, wresting areas in the east from rival Taliban insurgents in a new threat to stability.
