Suspicion for the blasts quickly fell on Kashmiri militants, who have repeatedly used near-simultaneous explosions to attack Indian cities.
Two Kashmiri militant groups on Wednesday denied playing any role in bombings.
But two of the main Islamic militant groups in the Himalayan region, Lashkar-e-Tayyaba and Hezb-ul-Mujahedeen, condemned the bombings in separate statements released Wednesday. They both insisted they had nothing to do with the Bombay bombings or a series of grenade attacks in Kashmir that killed eight people earlier the same day, the AP reports.
The Hezb-ul-Mujahedeen militant group also condemned the blasts and said in a statement that "Mujahedeen cannot be involved in such heinous crimes."
