Pakistan seeks to ban former PM Imran Khan's PTI party

Pakistan is seeking to ban former prime minister Imran Khan's political party - the Pakistan Tehreek-e-Insaf (PTI). It is also pressing the country's top court to file treason charges against him. His aide says the moves show there is "undeclared martial law" in Pakistan. This comes days after a landmark ruling by the Supreme Court in a post-election dispute, which saw the PTI granted more parliamentary seats. CNA's Hira Mustafa has more from Islamabad.
