Pakistan-based militant groups are making "concerted" efforts to push terrorists into Jammu and Kashmir to disturb the prevailing peace there, Union home secretary RK Singh said on Wednesday.
He said there have been increased infiltration attempts from across the border, possibly with the aim to sending more terrorists into Jammu and Kashmir before the onset of winter.
"The militant groups are making concerted attempts to push the terrorists through the border. Security forces are dealing with them," he told reporters in Delhi.
Sources said inputs indicated that some terrorists belonging to Hizbul Mujahideen, Lashker-e-Taiba and Jaish-e-Mohammed had crossed into the state during May while some more entered it by early July.
The terrorists have started using infiltration routes from Uri and Nowgam sectors in Kupwara in North Kashmir that were being used in the 1990s and early 2000 and which have been since been lying dormant, the sources said.
Moreover, there is a spurt in the frequency of infiltration attempts this year. The week-on-week comparison with last year's data shows that while two attempts were made during this period in 2011, this year the number has been 10, the sources said.
