The Indian Parliament attack occurred on December 13, 2001, when five armed terrorists from the militant group Lashkar-e-Taiba and Jaish-e-Mohammed stormed the Parliament building in New Delhi. They opened fire, resulting in the deaths of nine people, including security personnel and a civilian. The attack was aimed at the heart of Indian democracy, as the Parliament was in session at the time. In response to the attack, the Indian government launched a massive security operation and increased military readiness along the India-Pakistan border. The incident heightened tensions between the two countries, leading to a military standoff in 2001-2002. The attack remains a significant event in India's fight against terrorism.
