Pakistan's military has condemned an air strike by Afghanistan-based US forces that killed 11 of its troops as a "cowardly attack". The incident happened inside Pakistan, near the border with Afghanistan, as US-led forces tackled pro-Taleban militants.

The US military confirmed it had used artillery and air strikes after coming under fire from "anti-Afghan" forces. It comes amid rising tensions between the US and Pakistan militaries.
