A suicide bomber has hit a UK embassy vehicle in the Afghan capital Kabul, with a foreign worker reported to be among five people killed.
The other four who died and more than 30 people wounded were Afghans, officials say. Most of the victims are reported to have been bystanders.
The attack, carried out by a car bomber, was claimed by the Taliban.
Taliban insurgents have stepped up attacks as most foreign troops prepare to leave Afghanistan next month.
Thursday’s huge blast occurred on a busy road and was heard across eastern parts of the city.
The British embassy four-wheel-drive was thrown on to its side by the explosion. Many nearby other vehicles were destroyed.
Earlier Afghan officials said the bomber had been riding a motorcycle.
The UK Foreign Office said it was “working with the Afghan authorities to establish details of the incident”.
The attack comes three days after two US soldiers were killed in a bomb attack on Nato forces, also in eastern Kabul.
President Ashraf Ghani, who came to power in September, has vowed to bring peace to the country after decades of conflict.
About 12,000 Nato soldiers are expected to remain to train and advise Afghan security forces from 1 January.
A separate US-led force will assist Afghan troops in some operations against the Taliban. The security pacts with Nato and the US are yet to be ratified by the Afghan upper house.
