No one has claimed responsibility for a trio of bomb blasts in India's commercial capital of Mumbai that killed at least 17 people and wounded dozens, as police sifted through clues Thursday to determine who might have carried out the attacks.
Government officials said they have yet to rule out any group or motive. Despite 2008 attacks by gunmen in the city blamed on Pakistan-linked militants, the officials have been careful not to point fingers at Islamabad for Wednesday's bombings.
