Taliban suicide bombers hit buses carrying Afghan soldiers in two separate attacks early Wednesday morning in Kabul, killing seven and wounding 21.
The attacks happened one day after the United States and Afghanistan signed a security pact that allows U.S. forces to stay in Afghanistan after the end of 2014.
Both buses were hit by suicide bombers on foot, Kabul's criminal investigation police chief Mohammad Farid Afzali said. The Taliban quickly took responsibility for the bombings, with spokesman Zabihullah Mujahid saying the agreement with the United States motivated the group and gave it "more morale" to fight. "They need to give more sacrifices to make their homeland free," he said.
