Pakistan's biggest city of Karachi is tense following a night of violence that has left 35 dead. The clashes ensued in the wake of the killing of a member of the dominant political party of the city on Monday.
At least 45 people have been killed in revenge attacks in the Pakistani commercial hub of Karachi.
Police say Raza Haider of the Muttahida Qaumi Movement, or MQM, was gunned down on Monday along with his bodyguard while attending a funeral.
The attack has apparently set off a new round of ethnic and sectarian-related clashes.
Karachi’s police chief says about 90 people were injured and dozens of shops and vehicles have been burned.
The MQM has called for three days of mourning. Schools are closed and traffic is minimal.

"Karachi is the most sensitive city of Pakistan. Such incidents cause not only great loss to this city but they also badly affect other cities like Hyderabad, Nawabshah and Sukkur."
The MQM draws most of its support from Urdu-speaking descendants of families that moved to Pakistan from India.

"This is all to ruin the economy of Pakistan. This is to restrict Muslims so they aren't able to do anything."
Government officials say criminals are taking advantage of the tensions, making policing even more difficult.
