Pakistan is holding a repeat election in an upmarket area of the southern city of Karachi that was plagued with allegations of vote-rigging.

The vote is going ahead Sunday despite the shooting death of a senior member of former cricket star Imran Khan's political party in Karachi the previous night.

Khan has blamed Zahra Shahid's killing on the Muttahida Quami Movement, the same party he accused of vote rigging in the May 11 election.

An MQM senator, Babar Ghori, denied the allegation.

Police officer Sarfaraz Nawaz said gunnmen shot Shahid on Saturday night as they tried to snatch her purse in front of her home and then sped away on a motorcyle.

He said they made it look like a robbery, but it could have been a targeted killing.
