Pakistani opposition figure Tahir-ul-Qadri has called on his supporters to march on Islamabad to topple the government.
The mass rally is planned for Thursday. Supporters of the populist cleric staged a massive anti-government rally in the city of Lahore on Sunday. Meanwhile, supporters of opposition leader Imran Khan will stage a similar rally in the capital. Both groups accuse Pakistani officials of corruption. They want the government to step down and hold fresh elections.
