Pakistan has announced plans to expel India's top diplomat and suspend trade with its neighbour, deepening a row between the countries over the disputed territory of Kashmir.
Indian‑administered Kashmir has been on lockdown since the Indian government decided to strip the region of its special constitutional status.
Phone networks and the internet have been cut off since Sunday evening.
Tens of thousands of troops have been patrolling the streets.
Instances of protest and stone‑throwing have been reported, despite the communications blackout and a curfew.
India and Pakistan ‑ both nuclear‑armed states ‑ have fought two wars over Kashmir, most recently clashing in a series of aerial attacks over the territory in February.
