Leader of Pakistan's opposition Jamaat-e-Islami party Sirajul Haq called on the government to apply bolder policies in relation to the Kashmir issue at a rally in Peshawar on Sunday.
"China continued its struggle [over Taiwan] for 100 years but was not tired. We will also fight for the liberation of Kashmir for 1,000 years. We will sacrifice our lives and will not step back, God willing," said Haq.
He also warned Prime Minister Imran Khan against accepting US president Donald Trump's offer to mediate with India over Kashmir.
Demonstrations continue across Pakistan after India stripped the disputed territory of its special status.
