Kabul blast outside India embassy

At least seven people have been killed and more than 60 injured in a large explosion in the Afghan capital, Kabul.

The blast occurred near the interior ministry office and the Indian embassy.

Officials said it appeared to be a suicide attack. An Indian embassy official told the BBC a part of a security wall had been damaged.

Kabul has witnessed a number of attacks in recent months. Last month six Italian soldiers were killed in a bomb attack on a military convoy.

Most of the attacks have targeted international forces or government offices.

The cause of the latest blast was not known.

Television pictures showed charred vehicles at the site and ambulances speeding to the location.

Nirupama Rao, India's foreign secretary told reporters, he believed "the suicide bomb was directed against the Indian embassy".

Three Indian paramilitary troops guarding the embassy received minor shrapnel injuries, he said.

The blast, which occurred at 0827 local time (0353 GMT), appeared to be the work of a suicide bomber.

One reporter at the scene said he had seen two cars damaged at the site of the blast.

A policeman at the scene told Reuters news agency that the explosion happened inside a car.

"I was busy working when the blast happened. The windows were shattered, I ran into my tent," a worker at a nearby construction site said.

In July 2008 a suicide bomber has rammed a car full of explosives into the gates of the Indian embassy in Kabul, killing 41 people and injuring 141.
