At least 11 people were killed and 30 injured in a suicide attack in Swat Valley in Pakistan's northwest, Aaj TV reported on Monday.

The attack on a military convoy believed to have been staged by a suicide car bomber occurred in Swat's main city, Mingora, the channel reported.

Local TV footage showed a car enveloped in flames. Earlier reports said six people were killed.

Pakistani military conducted a major offensive in the valley, formerly a popular tourist destination, last year to retake it from Taliban control.

The military said they had largely cleared the area from Islamists after months of fighting. But sporadic clashes and suicide attacks continue to rock the area.
