Pakistan's parliament is holding an emergency meeting Tuesday as part of efforts to rally political support for Prime Minister Nawaz Sharif, who is refusing to resign despite weeks of opposition protests.
Thousands of protesters have occupied a central part of the Pakistani capital for more than two weeks, demanding that the prime minister resign over alleged election fraud.
The protests have been mainly peaceful until this weekend when clashes erupted between protesters and security forces.
Monday witnessed more pitched battles between protesters and police.
Demonstrators briefly took over Pakistan's state television station, forcing the channel off the air.
