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 set off with a few hundred people. Mr Khan, like many Pakistanis, says the attacks kill large numbers of civilians and foster support for militants.
"No-one should be allowed to be judge, jury [and] executioner," Mr Kahn said before setting off.
"It's totally counter-productive. All it does is it helps the militants to recruit poor people. Clearly if they were succeeding, these drone attacks, we would be winning the war. But there's a stalemate."
