Guru was an operative of Jaish-e-Mohammad (JeM) that is led by Maulana Masood Azhar. Masood Azhar was freed from Indian prison along with two more terrorists in 1999 during the IC-814 hijack in swap for passengers who had been held hostages in Kandhar of Afghanistan.
After being released by Indian authorities Azhar found Jaish in Pakistan with full state patronage.
But after involvement of some of Jaish operatives in the attack on the then Pakistani president general Pervez Musharraf became known, the ISI sidelined Masood Azhar.
But now with Afzal Guru's hanging Jaish may try to make a comeback.
Jaish is known for its strikes on high-security targets like Jammu and Kashmir state assembly building, the Parliament house and the makeshift Ram temple in Ayodhya.
Besides, other terror outfits like Lashkar-e-Taiba may try to exploit the situation in Jammu and Kashmir and elsewhere. All border security forces in Jammu and Kashmir have been asked to remain on high alert.
Similarly, the Delhi police was asked to remain alert even before the hanging. Commissioner Neeraj Kumar was kept in the loop as the hanging had to take place in Delhi's Tihar jail.
Additional security measures were put in place with intensified patrolling. All deputy commissioners have been asked to remain present in their respective areas.
The Centre has asked all states to remain vigilant after the hanging.
