Mumbai's terror track record: nine major attacks in two decades

Yesterday's blasts in Mumbai prompted Indian newspaper Hindustan Times to ask: "Why is Mumbai targeted again and again?"

Car bombs kill more than 250 in 1993

Two hundred and fifty-seven people were killed in March 1993 when 13 car bombs went off at various points in the city, including the stock exchange. The attack, which also injured more than 700 people, came on the heels of Hindu-Muslim violence in the city in which many working-class Muslims were killed by Mumbai police. The attack was attributed to mob boss Dawood Ibrahim, allegedly as revenge for the large number of Muslims who were killed in the riots.

2002-03 bombings

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.

2006 train bombings blamed on Pakistani intelligence

In July 2006, seven blasts in separate locations on local trains killed 186 people. Indian officials blamed the attacks on Pakistan-based militant group Lashkar-e-Taiba and domestic group Students Islamic Movement of India and said they were acting on behalf of Pakistani intelligence agency Inter-Services Intelligence (a claim that Pakistan denied), according to a BBC report from 2006.

The incident brought Indian-Pakistani relations to a low point, with Pakistan furious with India for placing blame on the Pakistani government.

2008 shooting sprees

The November 2008 three-day assault on Mumbai included shooting sprees that left more than 150 people dead. Gunmen linked to Lashkar-e-Taiba rampaged throughout the city's luxury hotels and cafes, putting India-Pakistan relations in a "deep freeze" as claims arose that the shooters had ties to the Pakistani military. Pakistan later acknowledged that some of the attackers were from Pakistan and carried out some of their plotting there.

The Monitor's New Delhi reporter says that for Indians the incident's significance is comparable to 9/11.

2011 blasts

There are still many unanswered questions after yesterday's series of bombings in Mumbai, which killed at least 17 people and injured more than 130. Investigators don't know yet who is responsible, or what their motivation was. What they do know is that bombs went off at rush hour in three different sites – in the Opera House district, near the Zaveri Bazaar, and near a transport hub in a suburb – and city residents want to know why, after 2008's deadly attack, something like this was able to happen.
