PESHAWAR, Pakistan (Reuters) - A suicide bomber attacked a funeral procession near the northwestern Pakistani city of Peshawar on Wednesday killing up to 20 people, a government official said.
The funeral was for the relative of a pro-government, ethnic Pashtun tribal elder, Peshawar's top administrator, Siraj Ahmed, told Reuters.
"Up to 20 people have been killed and the toll could rise," said Ahmed, adding that more than 50 people had been wounded.
The attacker mingled with the mourners before setting off his explosives, he said.
There was no immediate claim of responsibility.
The attack came a day after militants set off a car-bomb at a natural gas filling station in the central city of Faisalabad killing 25 people and wounding about 125.
Pakistani Taliban fighting to bring down the U.S.-backed government claimed responsibility for that attack.
Pakistan has seen a wave of bombs in the past three years, many in the northwest near the border with Afghanistan, where the military is battling al Qaeda-linked Pakistani Taliban insurgents.
The army says that several military offensives have weakened the militants but bomb attacks are still common.
