Media reports say a series of explosions have hit the western Indian city of Ahmadabad. The TV reports say the blasts went off in several neighborhoods of the busy city on Saturday evening. There was no immediate police comment and it was not clear if there were any casualties. Several Indian cities have been hit by serial blasts in recent months. The attacks have been blamed on Islamic militants. Saturday's blasts come a day after seven small explosions hit the southern technology hub of Bangalore, killing two people.
