"We have information that Pakistan is helping terrorists to enter our territory. We have intelligence inputs. But we are alert," he told media persons in New Delhi.
The home minister said his ministry has directed all concerned to be extra vigilant during the ongoing festival season and ensure peace. "I also appeal people to be extra careful," he said.
Referring to Jammu and Kashmir, Shinde said security forces cannot be withdrawn from the Valley till the situation is completely peaceful there.
"When I was in Jammu and Kashmir, locals asked me to remove the Army from the Valley but I told them that we can't do it till the situation is peaceful. We will remove the Army when the situation is peaceful," he said.
On the anti-corruption movement of Arvind Kejriwal-led India Against Corruption, the home minister said the activists should introspect as their acts were "creating indiscipline" in the society and the government would not tolerate it.
"They are creating indiscipline. This is illegal. If someone takes law in his hands, we would not tolerate it," he said.
Referring to Kejriwal's action of restoring electricity connection of an individual during his protest on water and power tariff in the capital, he said such acts were unacceptable as the supply had been stopped due to non-payment of bill.
Shinde said he had visited the Indo-Bangladesh border on Saturday and assessed the situation there.
Earlier, while attending the Police Commemoration Day, Shinde paid tribute to 575 security men who laid down their lives in the last one year.
While 383 personnel from state police forces were killed between September 1, 2011 and August 31, this year, 192 troopers belonging to central armed police forces died during that period.
