A Dec. 2, 2002 bus explosion that killed two and injured 31 was the first in a slew of bombings that took place over several months. Days after the bus blast, a bomb hit a Mumbai food plaza, injuring more than two dozen people. Thirty people were injured in January when a bomb planted in a bicycle went off outside a shopping complex. In March, 11 were killed and 65 injured when a bomb exploded in a women's compartment on a train pulling into a Mumbai station.
After a couple months of calm, attacks resumed. In August, two bombs went off in cars parked near city landmarks the Gateway of India and the Zaveri Bazaar, killing 46 and injuring more than 160.
