Parties and unions in Greece are to hold anti-fascist demonstrations in the country amid police investigation into alleged crimes committed by neo-Nazi Golden Dawn party.
Greece’s mainstream parties called on people to attend demonstrations in Athens and other cities on Wednesday evening.
"We call all institutional and social institutions to mobilize," the socialist Pasok party said.
The country’s main opposition party, Syriza, also called for a "peaceful march in defense of democracy."
The demonstrations came after the killing of a leftist musician by a suspected member of the far-right party.
Pavlos Fyssas, a 34-year-old hip-hop singer and an anti-fascist activist, died in a state hospital on September 18 after being stabbed twice outside a cafe in Keratsini in western Athens.
A 45-year-old man, George Roupakias, was arrested at the scene and later charged with voluntary manslaughter and illegal possession of a weapon.
Officials of the far-right party denied any links with the suspect, but pictures soon emerged of Roupakias participating in party activities such as the controversial distribution of food to ethnic Greeks only.
Golden Dawn has recently been accused of prompting beatings against migrants and political opponents, and that some of the party’s lawmakers have been involved in attacks.
On Tuesday night, police raided the party’s offices in central Greece and arrested a 45-year-old officer as part of the probe into links between police and the neo-Nazi party.
The government also suspended several senior police officers after the murder of Fyssas, for failing to probe the party’s suspected illegal activities.
