Police in the southern Indian city of Hyderabad say at least three people have been killed and about forty others wounded in communal clashes between Hindus and Muslims.

A spokesman said police opened fire in several different places to disperse rioters who attacked one another with swords, knives and stones.

A curfew has been imposed in parts of Hyderabad.

Correspondents say the trouble began on Friday after a provocative leaflet had been circulated.
