Security has been beefed up in north Kashmir ahead of a G20 meet in the valley later this month, in view of three back-to-back encounters with militants in which five ultras were killed, officials said on May 7.
Additional security personnel have been deployed on the ground and drones are being used for aerial surveillance, they said.
Sniffer dogs are assisting security personnel in checking vehicles at various checkpoints established to prevent the movement of militants or explosives, they said.
