Peshawar, Aug. 31 (AP): Attackers hurled a hand grenade at the Indian consulate in Afghanistan’s eastern city of Jalalabad, damaging a wall of the building and shattering windows, Afghan police said today.

No injuries were reported.

The drive-by attack occurred late yesterday in Jalalabad, the capital of the Afghan province of Nangarhar, provincial police chief Gul Karim said by satellite telephone.

Witnesses spotted four people driving by the consulate in two cars. The hand grenade was tossed into the building from one of the cars before they sped away, Karim said. There was no immediate claim of responsibility.

The consulate was closed at the time of the attack.

The blast left a hole in the front perimeter wall of the building and broke some windows inside, he said.

Police detained four Afghan men after they were caught speeding on a road near the consulate immediately after the explosion.

Earlier, attacks targeting aid workers and UN agency offices in Jalalabad have been blamed on Taliban insurgents.

Indra Manipandy, first secretary of the Indian embassy in Kabul, confirmed there had been an attack and that nobody was hurt.

He said the embassy had sent its security officer to the consulate to establish what happened.
