India has suffered a wave of bombings in recent years, withtargets ranging from mosques and Hindu temples to trains. It isunusual for any group to claim responsibility for attacks.
Islamist militant groups in Pakistan and Bangladesh intenton fanning hatred between Muslims and Hindus in India, anddamaging a fragile peace process between New Delhi andIslamabad, are often blamed.
In May, eight bombs, many strapped to bicycles, rippedthrough a crowded shopping area in the western city of Jaipur,killing at least 63 people and injuring hundreds more.
Police said that attack bore some hallmarks of theBangladeshi militant group Harkat-ul-Jihad al Islami (HuJI).
Bangalore also hosts vibrant biotechnology and aerospaceindustries as well as a garment sector employing more than300,000 people.
Indian shares initially extended losses on Friday afterreports of the blasts in Bangalore, but later recoveredslightly.
The 30-share BSE index ended down around 3.4 percent,driven by rising oil prices and falls in regional markets amidconcerns about the U.S. economy.
