India's major cities were put on high alert on Sunday, with fears of more attacks after at least 40 people were killed in two days of bombings that hit a communally-sensitive western city and a southern IT hub
At least 16 small bombs exploded in the Indian city of Ahmedabad on Saturday, killing at least 39 people and wounding 110, a day after another set of blasts in Bangalore killed a woman.
A little known group called the "Indian Mujahideen" claimed responsibility for the Ahmedabad attack on Saturday. The same group said it carried out bombs attacks that killed 63 people in the western city of Jaipur in May.
It is unusual for any group to claim responsibility, but India says it suspects militant groups from Pakistan and Bangladesh are behind a wave of bombings in recent years, with targets ranging from mosques and Hindu temples to trains.
"The entire nation, including major metro cities in India have been put on high alert and they have been asked to step up security in vital installations," a home ministry spokesman said.
In New Delhi, police used loudspeakers and distributed leaflets in crowded market places, warning people to watch out for unclaimed baggage and suspicious objects. Police guarded Hindu temples in the eastern city of Kolkata.
There were two separate series of bombings in Ahmedadad, the first near busy market places. A second quick succession of bombs went off 20 to 25 minutes later around a hospital, where at least six people died, police said. All were detonated with timers.
"I came with my two children to cheer up my mother admitted to hospital," said Pankaj Patel, whose son Rohan and daughter Pratha were killed at Ahmedadad hospital. "They were laughing when the blast occurred. Now they are dead."
Two doctors were killed in the hospital in a blast in which at least one bomb was tied onto a gas cylinder. Charred motorcycles and bicycles were shown outside. TV showed victims writhing in pain and covered in blood on hospital floors.
The other bombs were in Ahmedabad's crowded old city dominated by its Muslim community. Many were packed into metal tiffin boxes, used to carry food, and packed with ball-bearings. Some were left on bicycles.
