Pakistan deployed heavy security forces in the national capital, sealed key roads and suspended mobile and internet services in certain areas as supporters of jailed former premier Imran Khan on Sunday geared up for a protest march towards Islamabad.

A convoy under the leadership of Khan’s wife Bushra Bibi and Khyber Pakhtunkhwa Chief Minister Ali Amin Gandapur left for Islamabad from Peshawar. Geo News reported that Bibi was part of the convoy that started from Peshawar, but the KP chief minister was leading the protest.
