An explosion has rocked the diplomatic area of the Afghan capital, Kabul.

The incidence which according to the police is a suicide attack on a foreign military convoy travelling through the area got at least 10 people killed and 60 injured.

A health ministry official said nine Afghans and a foreigner were killed.

No group has said it carried out the attack, although in recent months Kabul has been regularly targeted by the Taliban in a series of bombings.

The explosion took place in Macroyan area, which is also not far from Kabul airport and the presidential palace.

An interior ministry spokesman quoted by the AP news agency said the blast destroyed more than a dozen civilian vehicles.

The bombing, close to a civilian hospital, is the latest in a series of recent deadly attacks following the announcement of a new Taliban leader.

Earlier this month, a Taliban suicide bomber attacked a checkpoint near the entrance to the international airport in Kabul, killing five people.

Before that, there were three deadly attacks in the city - on a police academy, a Nato base and an Afghan army base that killed at least 50 people.

The Taliban has stepped up its campaign of violence in recent months, taking advantage of the warmer weather of spring and summer. It has made some military gains, especially in northern Afghanistan.
