The BSF said a mob had attacked its camp, indulged in firing and tried to storm their storehouse of arms and ammunition around 6.30am.
According to locals, the protests erupted because BSF personnel had roughed up a religious leader’s brother on Wednesday night following an argument over offering late-night prayers during Ramzan.
The BSF dismissed the allegation. Inspector General of BSF Jammu Frontier Rajeev Krishna said a picket of troops of 76 Battalion of BSF had intercepted a person moving in suspicious circumstances at a check-point around 10pm on Wednesday.
He refused to give details about his presence. The BSF team let him go and informed the police, the IG said. As the police were investigating the matter this morning, a mob of 700-800 people attacked the BSF post with stones injuring one constable, Krishna added.
"Keeping in view the threat to the arms and ammunitions, steps were taken with maximum restraint by the security forces."
Asked if the deaths were due to BSF firing, Krishna said, “BSF and police officials and officers were on the spot. It is difficult to say in whose firing the casualties were caused.”
In Delhi, Union home minister Sushilkumar Shinde ordered an inquiry into the firing. "I assure that any use of excessive force or irresponsible action shall be dealt with strictly," he said in a statement.
