In pictures: Delhi blasts

A series of bomb blasts has hit busy shopping areas in India's capital, Delhi, killing at least 20 people and injuring 90 others, officials say.

Police say there were five bombs which exploded within minutes of each other.

One of the blasts occurred in the upmarket shopping district of Greater Kailash, in the south of the capital.

Victims of the blasts were soon arriving at nearby hospitals, amid fears that the death toll would rise further.

A number of people were seriously injured, requiring urgent medical attention.

Four unexploded bombs were also found and disarmed, police said.

The explosions are not thought to have been very powerful but they happened in areas crowded with evening shoppers.

Nearby property was badly damaged by the explosions.

A group calling itself the "Indian Mujahideen" - whose origins are unclear - claimed responsibility for the blasts.
