Big anti-corruption demo in Islamabad Tens of thousands of people remain on the streets of Islamabad after a call for a peaceful revolution from the Sunni cleric Tahirul Qadri. Back from exile in Canada, he wants the military and judiciary to install a caretaker government in Pakistan to oversee the upcoming elections. His call has divided the population. Some see Qadri as a champion of reform. Things turned nasty at first light as police fired rubber bullets and tear gas as crowds converged on the parliament building. Qadri, a moderate, is thought to want to encourage peaceful demonstrations similiar to those in Cairo's Tahrir Square that ended in the fall of Egyptian President Hosni Mubarak.
