Officials say a suicide bomber riding a motorcycle has struck a British Embassy vehicle in the Afghan capital, Kabul, killing at least five people, including a foreigner.
The nationality of the foreigner could not be immediately confirmed, and the British Embassy had no comment.
Earlier, an embassy spokesman confirmed the attack and said some people in the vehicle were wounded, without providing further details. The vehicle was not carrying any British diplomats, the spokesman said.
The blast wounded 33 Afghan bystanders and destroyed three cars, Interior Ministry spokesman Sediq Sediqqi said on November 27.
Afghan Public Health Ministry spokesman Kanishka Bektash Turkistani said the wounded included five children.
Police officials say the incident took place in the eastern part of the city on the Kabul–Jalalabad highway.
Eyewitnesses say the powerful blast shook parts of Kabul and sent a massive plume of dust and smoke into the air.
The blast reportedly shredded the four-wheel-drive embassy vehicle, leaving a charred shell lying on its side.
The Taliban claimed responsibility for the attack, saying the suicide bomber "targeted foreign invading forces."
The area of the blast has many foreign compounds and international military installations.
In recent weeks, insurgents have launched attacks on military convoys in the area and on compounds housing foreign service companies and their international employees.
On November 24, two NATO soldiers were killed and a civilian wounded in a bomb attack in that area.
Kabul has come under almost daily attack as insurgents intensify their war on local security forces and U.S. and NATO troops, who are set to officially conclude their combat role in the country at the end of December.
Britain ended its 13-year military presence in southern Afghanistan this week when the last Royal Air Force personnel departed from Kandahar airfield.
