Pakistani police say gunmen riding on a motorcycle opened fire and seriously wounded a senior leader of a party that is influential in the southern port city of Karachi

Officer Mushtaq Mehar says Rasheed Godil from the Muttahida Qaumi Movement was targeted Tuesday as he was leaving a marketplace. He suffered multiple gunshot wounds and his driver was killed.

Mehar says Godil had been taken to hospital in critical condition.

No one immediately claimed responsibility for the attack.

Last week, MQM lawmakers quit the parliament to protest what they called a military crackdown against the party and its supporters in Karachi. Authorities say they are conducting an anti-crime operation in the city.

MQM is headed by Altaf Hussain, who has been living in self-imposed exile in London since early 1990s.
