Besides, at least 90 Pakistani infiltrators entered India through the India-Pakistan border this year. At least 125 militants were also apprehended along the border in Jammu and Kashmir while trying to infiltrate into India.
The huge jump in the number of Pakistani infiltrators -- from 63 in 2011 to 90 this year -- sent alarm bells ringing in the home ministry, which directed security agencies to intensify vigil along the border.
Altogether 94 Pakistani infiltrators have entered into India in 2010 and 69 in 2009 through the Indo-Pak border.
There have been a total of 249 infiltration attempts this year as against 247 last year. There were 489 infiltration attempts in 2010, 485 in 2009, 342 in 2008 and 535 in 2007.
The sources said these attempts were being made with the active help of Pakistan Army which often gives firing cover to the militants.
