Jammu, Aug 16: There was an exchange of fire between suspected infiltrators and Border Security Force (BSF) personnel on the border with Pakistan in Ramgarh sector near Jammu, officials said on Sunday.

According to BSF officials, there was some movement noticed by the guards late Saturday night near the barbed wire fence erected to prevent intrusion inside the Indian territory.

"The BSF troopers challenged and as result there was firing from a suspected group of intruders," an official said.

The firing continued for two to three hours, the official said. "We assume that the intruders escaped back into Pakistan but we are conducting searches," he said.

Unconfirmed reports say that a portion of barbed wire fence was cut, suggesting possible intrusion. But BSF officials refused to comment.

The security forces including BSF, army and police are conducting extensive searches and alert has been sounded on the Jammu-Pathankot highway. Ramgarh sector is 15 km from the highway.
