A mob is reported to have attacked supporters of the Indonesian opposition leader, Megawati Sukarnoputri, in a town south of Jakarta.

The secretary general of the Megawati faction of the Indonesian Democracy Party, Alex Litaay, said about 50 people attacked a group of its supporters in the town of Kopo, about 70 kilometres south of the capital.

Mr Litaay did not say who might have organised the attack, but said the mob used sticks and stones in the assault.

He said his party members had gathered to protest against a national party meeting of the government-backed faction led by Suryadi, who deposed Ms Megawati at a party congress last year.
