The sources said the Pakistanis reached the post since it was located close to the fence near the LoC, which divides Kashmir between India and Pakistan.
The Indian Army has erected a three-tier fence in Indian territory running along the LOC. The fence is about 500 metres to two kilometres inside Indian territory and seeks to prevent Pakistani intrusion.
But the Pakistanis sneaked in using the fog in the forested area as a cover, an army spokesman said.
"The (Indian) patrol spotted them and engaged the intruders" for about half hour after which the Pakistani troops retreated, he said.
