Pakistan's Imran Khan leads protest against US drone strikes

Cricketer-turned-politician Imran Khan has begun a motorcade "march" to Pakistan's restive tribal areas to protest against US drone strikes.

The two-day protest started in Islamabad and is due to end in South Waziristan, a major focus of strikes.

Mr Khan, like many Pakistanis, says the attacks kill large numbers of civilians and foster support for militants.
