Speaking to reporters, Kapoor said, "The solution to this problem lies with our neighbouring country as they provide support to these terrorists for infiltration."
He was replying to a question when asked if there was any solution to the problem of terrorists infiltrating from Pakistan into India.
He said the militants would continue to infiltrate in future also as they had the support of the "organisation on the other side."
Kapoor ruled out taking any action against terrorists before they entered Indian territory and said, "We can't take action against them till the time they cross over to our side."
Last week, eight militants were killed by security forces during an encounter along the LoC in Kupwara district in Jammu Kashmir.
Commenting on the incident, Kapoor said, "When they tried to infiltrate, we detected them. After detection, we engaged them and after that eight militants were killed and the remaining went back to the other side of the Line of Control as our troops were alert."
