Powerful explosion heard in downtown Kabul

A powerful explosion rocked downtown Kabul on Monday evening, according to AFP reporters, the second blast of the day to hit the Afghan capital.

Officials were trying to determine the exact location of the explosion and there were no immediate reports of casualties, Kabul police spokesman Abdul Basir Mujahid told AFP.

An interior ministry spokesman said the blast was caused by a car bomb.

Earlier Monday, a suicide bomber struck a street leading to Kabul's international airport, but no casualties were reported.

No group immediately claimed responsibility for the bombings, which comes as Afghan forces battle to end an hours-long siege near the Indian consulate in the northern city of Mazar-i-Sharif.

The bombings mark the latest assaults on the war-scarred Afghan capital.

A Taliban suicide car-bomber struck a French restaurant popular with foreigners in Kabul on Friday, killing two people in a New Year's Day attack.

Fifteen others were wounded in the attack on Le Jardin, an Afghan-owned eatery, which caused a piercingly loud explosion and left a building engulfed in flames.
