The bomb was found in front of Fahim's house in the Karta-Parwan district of northwest Kabul, Kabul television said. Fahim is currently in Germany on an official visit.

It was the third suspected attempt on General Fahim's life, the report said.

On a visit to Jalalabad last year, Fahim's convoy was hit by a massive blast from explosives hidden inside a generator beside the road. Several people were killed but Fahim was unhurt.

And earlier this year police arrested a man with C-4 explosives strapped to his body near one of Fahim's other houses in the upmarket Wazir Akhbar Khan district of Kabul.

Several bombs have been found in the Afghan capital over the past few days as security forces remain on high alert following a suicide bomb attack on German troops.

And the United Nations Tuesday warned its staff of another possible suicide bomb attack over the next two or three days using Japanese cars and motorbikes.

A bomb was discovered and defused outside a Kabul high school on Monday. Another device was found Thursday on a road in northwest Kabul.

Four German peacekeepers were killed in a suicide car bomb attack in Kabul on June 7 which wounded 29 other troops and also killed an Afghan passerby.

Interior Minister Ali Ahmad Jalali last week warned of further suicide attacks against foreign troops.

It is not known who carried out the attack on the peacekeepers but the German and Afghan governments have blamed it on Osama bin Laden's al-Qaeda network.

The Taliban's refusal to surrender their "guest" Osama bin Laden led to the US-led operation to topple the militia after the September 11, 2001 attacks on New York and Washington.
