A powerful vehicle bomb has hit the diplomatic area of the Afghan capital, Kabul, killing at least 80 people and injuring 350.
It struck near Zanbaq Square in the heavily fortified zone, with civilians said to be the main casualties.
The morning rush-hour blast was so strong it blew out windows and doors hundreds of metres away.
The Taliban have denied they carried out the attack. There has been no word so far from so-called Islamic State.
Both groups have been behind recent attacks in the country.
The BBC has said that Mohammed Nazir, a driver for the corporation’s Afghan service, died in the explosion.
