Police and protesters clash as jailed leader urges ‘fight to the end’

Thousands of protesters have breached barricades around Islamabad, clashing with police who fired tear gas to disperse the crowds and block their advance. Imran Khan, former Prime Minister of Pakistan, has called on his supporters to "fight to the end" against what he describes as a "mafia" imposed on the country. The protests, led by Khan’s political party, accuse the government of holding him on politically motivated charges. Fahd Husain, Pakistani journalist, joins CNN's Becky Anderson to discuss. #CNN #News
