Police cracked down on the latest demonstration in the northern city of Lahore - arresting several leaders of the Pashtun Protection Movement.

The PTM rose to prominence after the police shooting of a young social media star in Karachi in January.

The death of Naqeekbullah Mehsud brought thousands onto the streets to urge an end to police impunity.

Ethnic Pashtuns say they've borne the brunt of the so-called war on terror in Pakistan - with thousands disappearing over the years or targeted in extra-judicial killings.
