Pakistani protest turns violent

Pakistan opposition leader Nawaz Sharif has defied an apparent house arrest order to head for a protest in Lahore.

Describing the order - denied by the government - as "illegal" he left his Lahore home urging people to join him.

Police fired tear gas at the stone-throwing protesters who plan to march to Islamabad to demand judges sacked by the former government be reinstated.

But Mr Sharif's car was allowed to drive through a police cordon as it approached the rally in central Lahore.
