Kabul

At least 13 officers of the Afghan National Police were reportedly killed, and 11 U.S. contractors are among the wounded, after a massive explosion near foreign embassies.

In addition to the deaths, three U.S. service members were wounded, as were 25 Afghan civilians, in the morning rush-hour attack that happened near the U.S. Embassy, a U.S. military spokesman says.

The blast struck near the Defense Ministry in the Afghan capital. Reporter Jennifer Glasse says that, according to witnesses, the second explosion targeted those aiding victims of the first.

Gunmen attacked the heavily fortified campus in the capital on Wednesday evening. At least 13 people died before Afghan forces killed the attackers.

Afghan authorities say that at least 80 people were killed and 231 were injured in the attack. The Islamic State claimed responsibility, saying it was targeting a "gathering of Shiites."
