A senior Pakistani politician, Dr. Imran Farooq, was stabbed to death outside his home in London, police said Thursday. Officers found the 50-year-old man with multiple stab wounds and head injuries outside an address in north London at about 5:30 P.M., police said in a statement. Farooq, a member of Pakistan's political party Muttahida Qaumi Movement (MQM), had been living in London since 1992 and had not returned to Pakistan since. He was pronounced dead at the scene, police said. No arrests were made and police were investigating the case. The Muttahida Qaumi Movement, based in the southern city of Karachi, is one of the country's major parties and has a strong anti-Taliban stance. The MQM's office in London did not pick up calls made late Thursday.
