The murder of a rap singer blamed on a supporter of the far-right Golden Dawn party has drawn widespread condemnation from across Greece's political spectrum.
Pavlos Fyssas, a 34-year-old hip-hop and rap singer described by colleagues as an anti-fascist activist, died early on Wednesday from two stab wounds to the chest after leaving a cafe in Keratsini, a suburb of Piraeus.
Hundreds attended his funeral on Thursday, chanting anti-fascist slogans, and many visited a make-shift shrine created at the site of the attack.
"This government is determined not to allow the heirs of Nazism to poison our social life, to commit crimes, to terrorise and undermine the foundations of the country that gave birth to democracy.
"Democracy is much more powerful than its enemies may think," Antonis Samaras, Greek prime minister, said in a televised address to the nation on Thursday.

Authorities said Fyssas identified the man who had stabbed him to police before collapsing.
The 45-year-old suspect was arrested, admitted to the killing and identified himself as a Golden Dawn member, police said.
He has not been named in accordance with Greek law.
He appeared before a prosecutor late on Wednesday and was given three days to prepare his defence.
He is due back in court Saturday.
His wife and two other people were also arrested on suspicion of attempting to conceal evidence linking him to Golden Dawn.
Golden Dawn leaders insist the party had nothing to do with the killing and have condemned the attack.
Greek media and blogs, however, have widely circulated the suspect's name and photos of him at numerous Golden Dawn events.
Golden Dawn supporters are notorious for carrying out violent attacks, mostly against immigrants, often causing severe injuries.
Greece's economy is mired in a deep recession currently in its sixth year, with unemployment at above 27 percent, and nearly 60 percent for those under the age of 25 - the highest levels in the EU.
