The 2001–2002 India–Pakistan standoff was a military standoff between India and Pakistan that resulted in the massing of troops on either side of the border and along the Line of Control (LoC) in the region of Kashmir. This was the first major military standoff between India and Pakistan since the Kargil War in 1999. The military buildup was initiated by India responding to a 2001 Indian Parliament attack and the 2001 Jammu and Kashmir legislative assembly attack. India claimed that the attacks were carried out by two Pakistan-based terror groups, the Lashkar-e-Taiba and Jaish-e-Mohammad, both of whom India has said are backed by Pakistan's ISI a charge that Pakistan denied. Tensions de-escalated following international diplomatic mediation which resulted in the October 2002 withdrawal of Indian and Pakistani troops from the international border.
