The Islamic State group's spokesman said its fighters are ready to battle a US-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 US President Barack Obama to form a global coalition against it. He said the group welcomed the possibility of a ground war with the US, and he called on Muslims worldwide to kill civilians of nations that join the coalition.
