A bomb disposal squad was called in to defuse the bomb that was found under Geo News anchor Hamid Mir's car by his driver.
The driver spotted the IED after Mir returned to his home in Islamabad from a nearby market.
The bomb, hidden in a black bag and packed into a tin, contained a locally made explosive, a detonator and a battery, the channel reported.
It aired footage of a member of the bomb disposal squad, clad in protective clothing, defusing the bomb.
No group claimed responsibility for the attempt on the life of Mir, who hosts a night-time talk show on Geo News.
