Police question 3 people over deadly bombing in Pakistan](http://www.kvia.com/Global/story.asp?S=7240992&nav=menu193_2)
KARACHI, Pakistan (AP) - Police in Pakistan have questioned three people over the deadly bombing of Benazir Bhutto’s caravan.
A senior investigator says the men are linked to a vehicle that police believe was used by 1 of the attackers who threw a grenade at the convoy late Thursday.
The grenade caused Bhutto’s campaign bus to come to a halt, and seconds later, a suicide bomber blew himself up with a shrapnel-filled explosive. At least 136 people were killed in the attack.
The senior investigator says police believed the men, who have yet to be charged, hold crucial clues on the bombing.
Pakistan’s government has denied involvement in the attack.
