Pakistani officials say a bomb blast near the Afghan border has killed at least 25 people and wounded 26 others, making it the deadliest attack of its kind in months.

Authorities say they believe it was a remote-controlled bomb that exploded in a market in the Khyber tribal region Tuesday. Eyewitnesses told reporters that the attack left many bodies scattered on the ground.

Near the site of the bombing were vehicles that were being used by pro-government militias. Pakistan's army supports the formation of local anti-Taliban militias, known as “lashkars,” and militants have continually attacked militia members and their families over the past few years.

While no one immediately claimed responsibility for the blast, this type of attack is a common tactic of Pakistan's militant groups in the country's volatile northwest.

Since 2007, Islamist militants — some with links to al-Qaida — have carried out hundreds of bombings in Pakistan, which have killed thousands. However, there had not been a major Islamist militant attack since a suicide bomber killed at least 31 people at a funeral for a tribal elder opposed to the Pakistani Taliban last September.

The Pakistani armed forces have targeted militants in Khyber and the surrounding areas for more than four years.
