A case has been registered against former incarcerated Pakistan Tehreek-e-Insaf founding chairperson Imran Khan and several party leaders and workers under serious charges of "rebellion and terrorism".

Pakistan’s capital was locked down on Saturday, swarmed by security forces with mobile internet cut as supporters of jailed ex-prime minister Imran Khan attempted to seize the streets in protest.

Hundreds of containers were placed in different parts of Lahore, including all entry and exit points Saturday to foil the PTI's protest.
