Footage apparently showing security forces firing on anti-government demonstrators in the Albanian capital, Tirana, has been shown on Albanian television.
Hospital sources say three civilians died from gunshot wounds during clashes on Friday but Prime Minister Sali Berisha and the opposition are blaming each other for the unrest.
And both sides are planning rallies in the coming days.
Since disputed elections in 2009, the Socialist opposition has staged many non-violent protests, including hunger strikes.
But after Friday’s unrest Berisha insisted he would not resign and would not allow a Tunisia-style revolt in Albania.
The burials of the victims of the violence have already begun.
The Socialist Party leader and Mayor of Tirana, Edi Rama, attended the first, promising more protests to get rid of what he called an “intolerable regime of thieves”.
