Clashes erupt at Pakistani anti-corruption march
Police in Islamabad have fired warning shots in the air and used tear gas against anti-corruption protesters on a march led by cleric Tahirul Qadri.
The clashes erupted after demonstrators threw stones at security forces outside parliament.
Mr Qadri, who is calling for electoral reform, left the city of Lahore on Sunday with thousands of supporters, and reached Islamabad late on Monday.
Authorities accuse him of trying to postpone elections due by May.
