Two US service members were injured in Iraq in a joint US-Iraqi raid overnight that killed “multiple ISIS operatives,” according to a Defense Department spokesperson.

The news of the joint mission comes just weeks after the U.S. announced that it had reached a new agreement with the Iraqi government to bring the American anti-ISIS military mission in the country to an end by next year.

There are about 2,500 U.S. military personnel in Iraq participating in a counter-ISIS mission. U.S. officials in September announced American troops will remain in Iraq as the two countries agree to a transition of the American-led mission against ISIS.
