A car packed with explosives exploded outside a mosque attended by Taliban members in the Afghan capital, killing at least seven people minutes after prayers had ended on Friday, the interior ministry said.
The explosion occurred in front of Wazir Akbar Khan mosque, not far from the fortified former Green Zone that housed many foreign embassies and NATO before the Taliban seized power in August last year.
The mosque is often attended by Taliban commanders and fighters.
Interior ministry spokesman Abdul Nafy Takor told AFP that at least seven people had been killed and 41 others were wounded, including children.
Italian-NGO Emergency Hospital said it had received 14 people from the blast, four of whom were dead on arrival.
The explosion occurred when worshippers were heading home, according to Takor, which said the explosives were placed in a car.
The exact number is not known yet, but all civilian casualties are civilians, said Khalid Zadran, Kabul police spokesman.
Unverified images posted on social media showed a mangled car engulfed in fire on a road outside the mosque.
