(CNN) Fourteen people were killed and 60 injured in a suicide bomb attack Sunday near Hamid Karzai International Airport in Afghanistan's capital of Kabul, according to a spokesman for Kabul's police chief.

Gen. Abdul Rashid Dostum, the exiled Afghan vice president, was the target of the attack, said police spokesman Hashmat Stanikzai. Dostum fled to Turkey last year amid accusations of torture and abuse of political rival Ahmad Eshchi, but he returned to Afghanistan on Sunday.

An attacker detonated a bomb after being identified by police near the airport, Stanikzai said. A police officer was one of the casualties of the attack.

The Islamic State claimed responsibility for the attack, according to SITE intelligence group.

The violence comes a week after the release of a UN report stating the number of Afghan civilians killed in the first six months of 2018 has reached a record high. Almost 1,700 civilians were killed from January 1 to June 30, a total higher than at any comparable time in the last 10 years, according to the United Nations.
