"Coming months are tough from security point of view. We have terror infrastructure in tact across the loC (line of control) and in the hinterland," the top army commander said. The army officer refused to share the number of guerrillas waiting across the loC to infiltrate into the Kashmir Valley."The number is related to security dynamics and I would not like to share the same with you. But, I must assure you there is perfect synergy between the security forces, especially the intelligence agencies, and we are prepared to face the challenge," he said. He said there has been snowfall on the loC, but so far not all of it was covered with snow and there were possibilities of infiltration.
