Jammu: An RSS leader and his security guard were killed on Tuesday when a militant opened fire at a health centre in Jammu and Kashmir's Kishtwar town, prompting authorities to impose a curfew and call the Army to maintain law and order in the communally sensitive region, officials said.

The incident took place at 12.30 pm when a militant barged into the health centre and started firing at the RSS leader, Chanderkant Sharma, they said. Sharma and his personal security officer Rajinder had gone to a health centre in Kishtwar.
