A suicide car bomber targeted the police headquarters in a minority Shia neighbourhood in western Kabul, setting off a huge explosion that wounded dozens of people, Afghan officials said.
Afghan officials said at least 14 people were killed and 145 were wounded when a car bomb detonated in Kabul on Wednesday, sending a massive plume of smoke over the capital and shattering windows far from the blast site.
The car bomb exploded near the entrance of a police station in western Kabul around 0430 GMT, interior ministry spokesman Nasrat Rahimi said.
The Taliban claimed responsibility for the attack. Violence is surging across Afghanistan and in Kabul as the US and the Taliban negotiate a peace deal ahead of elections planned for September 28.

"I heard a big bang and all the windows of my shop broke, with glass flying everywhere," shopkeeper Ahmad Saleh said.

According to footage on social media and witnesses, small-arms fire could be heard following the blast.
