Helicopters are playing a vital role in the relief operation after last week's earthquake centred in Pakistani-administered Kashmir.

Chaklala airbase at the garrison city of Rawalpindi bursts into activity at 0630 every day.
The helicopter operation has already saved thousands of lives, the army says.
