Five bombs have ripped through busy shopping areas of India’s capital, Delhi, within minutes of each other, killing at least 18 people, police say.
The explosions, which also injured about 80 people, are not thought to have been very powerful but happened in crowded areas.
Two unexploded bombs were also found and defused, police said.
More than 400 people have died since October 2005 in bomb attacks on Indian cities such as Ahmedabad and Bangalore.
India has blamed Islamist militant groups for these previous bombings.
