Clashes have taken place overnight in the Iranian capital, Tehran, following anti-government protests on Sunday in which at least eight people died.
Reports say police fired tear gas to disperse crowds of demonstrators in various parts of the city overnight.
The nephew of opposition leader Mir Hossein Mousavi was among those killed in Sunday’s clashes, the worst violence since June’s contested elections.
His funeral on Monday is thought likely to be a focal point for more protests.
According to Mr Mousavi’s website, Seyed Ali Mousavi was shot in the back as security forces fired on demonstrators.
On Monday, state-owned English-language Press TV said eight people had died. Earlier, Persian state television had reported at least 15 people killed.
Police denied being responsible for any of the deaths. They said three were accidents and that one person had been shot, but not by police. Details of the others have not been given.
Officials said the shooting was under investigation.
