The Pakistani army says airstrikes have killed 30 militants near the Afghan border.

An army statement Wednesday says the airstrikes in the Khyber tribal region's Tirah Valley also destroyed two arms and ammunition depots.

It's the latest strike in a days-long army offensive in the area, home to the Pakistani Taliban and its allies. The army said the operation killed 80 militants and seven Pakistani soldiers over the weekend.

Pakistan has stepped up anti-militant efforts after the Taliban attacked a school in December in the northwestern city of Peshawar, killing 150 people — mostly children.

The Taliban have been launching attacks for more than a decade in a bid to overthrow the government and install their own harsh brand of Islamic law. Thousands have been killed.
