Police say the death toll in a pair of bombings targeting marches by minority Shiite Muslims in Pakistan's two largest cities has risen to 14 people.

Police official Tanveer Ahmed said Wednesday that four people died in the southern port city of Karachi a day earlier when a bomb hidden in a motorcycle exploded as a policeman protecting Shiite marchers tried to move it.

Authorities originally said Tuesday evening's attack was carried out by a suicide bomber and two people were killed.

About an hour and a half before the Karachi attack, a suicide bomber detonated his explosives in the eastern city of Lahore as policemen protecting a Shiite procession tried to search him, killing 10 people and wounding dozens.

The Taliban claimed responsibility for the Lahore attack.
