Morning Rush at Kabul Struck by Bomb

KABUL, Afghanistan — Witnesses say a bomb has exploded close to Afghanistan's Interior Ministry at central Kabul.

The blast happened during the morning rush hour today on a busy street in the city center. Ambulances were ferrying the injured from the scene.

It is not immediately known whether anybody was killed.

While Afghanistan has seen increasing violence in recent months, the capital has been largely spared from random bomb attacks that Taliban militants use in their fight against Afghan and international troops.
