Pakistani security agencies investigating last week’s deadly suicide attack on Benazir Bhutto have held at least 15 people for questioning, a police official said today.

Police in Pakistan are questioning three people over the bombing of Benazir Bhutto’s convoy, which killed at least 136 people and shattered what was intended to be a triumphant return from exile.

BENAZIR BHUTTO’S return to Pakistan yesterday was marred by a bomb attack in which up to 125 people, including 20 police officers, are reported to have been killed.
