More than 60 others were injured when an explosives-laden car targeted a building housing an anti-terrorist wing of the federal investigative agency on March 8.

The large explosives brought down the two-storey building, correspondents say, adding that a nearby religious school was also damaged.

Although nobody has claimed responsibility for the attack yet, Pakistan's government condemned the blast, blaming "hired killers who want to destabilise Pakistan".

The police said that the blast took place at a building housing the offices of the Special Investigation Group, an anti-terrorism wing of Pakistan's Federal Investigation Agency (FIA) in the Model Town area of Lahore.

Lahore has been hit several times by militants over the past year. Last December, two bomb blasts at a busy market killed at least 48 people and injured more than 100.
