A powerful vehicle bomb has hit the diplomatic area of the Afghan capital, Kabul, killing at least 80 people and injuring 350.

It struck close to the German embassy in Zanbaq Square, with civilians said to be the main casualties.

The wounded staggered from the site of a blast so strong it blew out windows and doors hundreds of metres away.

No group has yet said it carried out the bombing but the Taliban and IS have both been behind recent attacks.

The bomb went off at about 08:25 local time (03:55 GMT) during the rush hour in the Afghan capital.

Makeshift ambulances carried wounded away from the scene as frantic relatives gathered at the cordoned-off perimeter of the blast site.
