A group of around six infiltrators have managed to sneak in from Pakistan in Jammu and Kashmir, NDTV quoting government sources has reported.
A trooper was injured in firing during the infiltration attempt, they said.
The army according to the news channel has said it was engaged in a major operation in Jammu and Kashmir for the second day in a row following what is believed to be the biggest infiltration attempt by terrorists from across the Line of Control in recent years.
Internet services and mobile phones have been suspended in the Uri sector of north Kashmir since Monday morning.
Officials said an infiltration attempt was detected late Saturday evening, coinciding with the fifth anniversary of the Uri attack in which 19 troopers were killed after two suicide attackers stormed a military installation on September 18, 2016.
The army said the operation to track down the infiltrators is underway and the exact situation on the ground is still unclear.
This is for the first time when phone services and the internet was suspended in the wake of a cross-border infiltration attempt.
