When did the attack an Indian Parliament happen?

Five terrorists rocked the Indian Parliament on 12th December, 2001. They rammed their vehicle into the car of Krishan Kant, the Vice President of India, who was inside the building at the time. Five policemen, a parliamentary security guard, and a gardener were killed by their firing, and eighteen others were injured. A terrorist wearing a suicide vest was shot dead as the vest exploded in gunfire. The four other gunmen were also killed.

 The attack was masterminded by Jaish-e-Mohammed, a militant group backed by Pakistan. Two days after the attack the Indian police arrested four prime suspects: Abdul Rehman Geelani, a Delhi University lecturer, Mohammad Afzal, Shaukat Hussain Guru, and his wife Navjot Sandhu. All of them were Indians. A death sentence was handed out to the three male terrorists. Mohammed Afzal’s death sentence was upheld, Geelani was acquitted, and Shaukat Hussain’s death sentence was changed and reduced to ten years imprisonment.
