BEIRUT (AP) — The Islamic State group’s spokesman said its fighters are ready to battle a U.S.-led military coalition, casting it as a historic clash between Muslims and their enemies and calling for attacks at home and abroad.

Abu Mohammed al-Adnani’s 42-minute audio statement, which appeared to be a rallying cry, was the group’s latest response to efforts by U.S. President Barack Obama to form a global coalition against it.
