KARACHI, Pakistan (AP) — A police officer says gunmen have killed four policemen in southern Pakistan.
Superintendent of Police Naeem Sheikh says the police were attacked Wednesday as they ate at a roadside restaurant.
No one has claimed responsibility.
Karachi is a metropolis of over 20 million people where Islamic militants and other armed groups have carried out attacks in the past.
The Muttahida Qaumi Party, which has long dominated local politics, quit the national parliament Wednesday to protest against a military crackdown in the city, saying its members were unfairly targeted.
The police killings came a day after the army said it had foiled a militant plot to attack Pakistan Independence Day celebrations on August 14. The army said it had carried out a raid in Karachi as part of the operation.

Pakistan's military says its security forces have arrested a "foreign-sponsored" group of militants who wanted to disrupt this week's Independence Day celebrations by carrying out a suicide attack in the southern city of Karachi.
The military said in a statement Wednesday it acted on a tip-off from intelligence agencies. It says security forces also seized an explosive-laden vehicle during last Sunday's raids in Hyderabad and Karachi, the capital of southern Sindh province.
It says the captured militants included Bakhat Zaman, the deputy chief of the Pakistani Taliban. The statement did not identify the foreign power authorities believed sponsored the militants.
Pakistan won independence from Britain on Aug. 14, 1947. Millions of Pakistanis mark the day each year in rallies and by hoisting the country's flags at home.
