Nearly 300 Whatsapp groups were being used to mobilise stone-pelters in Kashmir to disrupt security forces' operations at encounter sites, of which 90 percent have been shut down, a police official said.

Each of these 300 Whatsapp groups had around 250 members, the official said while explaining how determined attempts were being made to disrupt the operations of the security forces by mobilising stone-pelting mobs at the encounter sites.

"We identified the groups and the group administrators, who were called in by police for counselling. We have had a good response to this initiative," he said on the condition of anonymity.

In the last three weeks, more than 90 per cent of these Whatsapp groups have been shut down, the official said.
