A small bomb exploded near the Indian consulate in the eastern Afghan city of Jalalabad on Tuesday, authorities said, after a series of attacks on Indian installations in the region.

The blast, which happened the morning after a gun and bomb siege near the Indian consulate in a northern Afghan city, was some 200 meters from the consulate in Jalalabad, an Indian diplomatic source said. The source and Afghan authorities said no one had been injured.

The explosion also follows a bloody weekend assault on an air base in India near the Pakistan border.
