At least 10 people were killed and 20 others wounded Sunday when a suicide bomber blew up a car outside the home of a local mayor in Pakistan's northwest Peshawar city, an official said.

"The toll is 10 dead and 20 injured," Peshawar district administration chief Sahibzada Anis told AFP.

"The suicide bomber came in a car and exploded it when the mayor was standing with some visitors outside his guesthouse near the local livestock market," Anis said.

The attack seriously wounded local politician Abdul Malik, who had raised a militia against Taliban rebels, police said earlier.
