Pakistan is staging what officials have called the country's biggest-ever military exercises.

The war games - which began on April 10 and will last for six-weeks - have been played out in the southeastern Cholistan desert, near the border with India.

It comes at a time when the country is engaged in a war with Taliban and al-Qaeda fighters and while tensions remain strong with neighbouring India.

The exercises have showed off an wide array of weapons from Swiss-made anti-aircraft guns to unmanned drones and a state-of-the-art battle tank.
