Asserting that 99 per cent infiltration attempts from Pakistan on the border have been foiled in Jammu and Kashmir this year, Director General of Police Dilbag Singh on Wednesday said the security agencies are fully alert and working to finish terrorism rather than just contain it. He said the border security grid is "much stronger than ever" with the addition of "new elements" to scuttle any attempt from Pakistan to push terrorists and smuggle arms and narcotics.
