At least four civilians died Saturday and another six were injured in a suicide attack against a convoy of the NATO-led International Security Assistance Force in Afghanistan, in the southern city of Kandahar, an Afghan official said.

The suicide bomber detonated explosives he was carrying in his vehicle as he passed a convoy made up of ISAF and Afghan troops in the Mandi Hissar district early Saturday morning, local government spokesman Javid Faisal told the local news agency AIP.

The fatalities were a woman and three children, according to the source.

The Taliban claimed responsibility for the attack.

"The attack was carried out by a suicide bomber in a vehicle and killed 15 soldiers," insurgent spokesman Zabiulla Mujahid told the AIP.

This attack comes during one of the bloodiest moments of the war in Afghanistan, coinciding with the gradual withdrawal of NATO forces and their replacement in 2014 on security missions by the army and police of the Kabul government.

On Friday, an attack against the U.S. Consulate in the western city of Herat left eight people dead. EFE
