The U.S.-led coalition in Afghanistan said that three service members were killed on Friday when a suicide car bomber attacked their convoy in an eastern district of the capital, Kabul.

The International Security Assistance Force didn’t provide details on the identities or nationalities of those killed.

Earlier, Kabul police spokesman Hashmat Stanakzai said the attack, which occurred about a kilometre (half mile) from the Camp Phoenix NATO base, wounded six civilians.

Taliban spokesman Zabiullah Mujahid said the insurgent group was behind the attack.
