Explosion in Kabul supermarket kills at least 3

The blast scattered debris across the street at the "Finest" supermarket several hundred yards from the British embassy and other diplomatic residences in Kabul.

A Reuters cameraman saw three dead bodies at the scene, including two women. Another three people were wounded, including a woman who appeared to be a foreigner. Fire blazed inside the building located on a busy roundabout.

It was not immediately clear what caused the explosion.

Violence in Afghanistan is at its worst level since the overthrow of the Taliban by U.S.-backed Afghan forces in late 2001 with record casualties on all sides of the conflict and a raging insurgency that has shown little sign of abating.

A "ring of steel" was erected around the capital before parliament elections last September, but this has not deterred militant attacks.

At least four people were killed when a suicide attacker rammed his motorcycle into a bus carrying security forces in Kabul earlier this month.

More than 30 people were also wounded in the attack, the third targeting security forces in the capital in less than a month.
