Pakistani police say gunmen have killed a senior member of the country's main Islamic party.
Police found the bullet-riddled body of the deputy chief of Jamaat-e-Islami's Karachi wing (Aslam Mujahid) east of the city. He was abducted hours earlier. Another official in the group blamed the rival Muttahida Qaumi Movement for the killing.
In other violence, a militant attack on a Shi'ite mosque in Karachi left five people dead. Police say officers killed two militants as they tried to enter the guarded mosque, while a third managed to get in and detonate a bomb strapped to his body. A worshipper and a police officer also died in the incident.
Witnesses say protesters went on the rampage after the attack, setting fire to an outlet of U.S. food chain KFC and four public transport vehicles.
