One policeman was killed and three others were wounded in the assault in the Raiwind area of Lahore, which came as a military operation against Taliban militants in the country's restive northwest enters its second month amid rising fears of reprisal attacks.

"A police team raided a house ... around 2 am [2100 GMT Wednesday] on a tip-off about presence of suspected militants, but they retaliated," senior police official Malik Owais told AFP.

"One terrorist has been killed and another injured in this operation has been arrested. Police have now occupied the compound," he added.

Waqas Nazir, another police official confirmed the incident, adding that the raid took several hours because civilians had to be evacuated from the area first.

Television footage showed a bullet-ridden compound with a large hole blown into one its walls being swarmed by police.

The Raiwind area is home to the famous "Raiwind Palace" - the residence of the powerful Sharif political family which also includes the chief minister of the Punjab province of which Lahore is the capital.

It is also the base of the Tablighi Jamaat, a Sunni Muslim evangelical movement known for its ultra-conservative views.
