3. The Delhi blasts
Terrorists struck Delhi on October 29 -- on the eve of Diwali and Eid, triggering three explosions in two city markets and outside a bus. At least 55 people were killed and 155 were injured.
The first explosion took place at 1740 IST in the busy Paharganj market. The market, which is frequented by foreigners, was bustling with shoppers.
Minutes later, another explosion rocked the Sarojini Nagar Market in south Delhi, where most of the casualties were reported.
Another blast took place 10 km further south in the Govindpuri area.
A month later, Tariq Ahmed Dar, allegedly a member of the Lashkar-e-Tayiba terrorist group and an award-winning sales executive at Johnson & Johnson, was arrested by the Delhi police for involvement in the crime. Delhi Police Commissioner K K Paul later claimed Dar had confessed to the crime, but his family denied his involvement in the blasts.
