Security personnel stand guard at the site of a suicide attack on the Supreme Court in Kabul, Afghanistan, on Tuesday, Feb. 7, 2017.

An Afghan official says that 10 police officers and the wife of a police commander have been killed by ISIS militants in northern Zawzjan province.

Mohammad Reza Ghafori, spokesperson for the Zawzjan provincial governor, said on Saturday that the police officers were ambushed on Friday as they were coming out of a mosque.

The wife of the police commander heard about her husband being shot and rushed to the scene, where she was also killed.

ISIS-linked militants have been active in Afghanistan’s eastern regions, but have recently begun operating in the north of the country as well.
