The murder of a politically active hip-hop singer by a member of the neo-Nazi Golden Dawn party added to the distress among Greeks on Wednesday amid ongoing social tension in a country experiencing record unemployment of 27.9 percent.

Pavlos Fryssas, 34, described by friends as an anti-fascist activist, died at hospital early Wednesday after suffering stab wounds outside a cafe west of Athens.

The 45-year-old assailant admitted to the attack and acknowledged a connection to Golden Dawn, which holds 18 of the 300 seats in the Greek parliament.

Police searched Golden Dawn offices in the capital on Wednesday as the rest of Greece's political parties condemned the killing and called for measures to rein in the neo-Nazi organization, whose "Black Shirts" squadrons are blamed for attacks on immigrants.

Golden Dawn lawmakers frequently engage in shouting matches on the floor of parliament and have assaulted leftist politicians during television discussion programs.

Black Shirts injured nine Communist Party activists in an attack last week in Athens.

The "savage murder ... shows in the clearest possible way the intentions of the neo-Nazi creation," Public Order Minister Nikos Dendias said Wednesday.

He said the conservative-led coalition government is looking at legal changes that would allow authorities to treat Golden Dawn as an armed band or criminal organization.

The leader of the main opposition Syriza coalition, Alexis Tsipras, urged his fellow leftists to concentrate on "democratic mobilization" and avoid being provoked to violence by groups that want to destabilize the state.

Fryssas, who performed under the name "Killah P," and some friends were at a cafe Tuesday night after attending a Champions League soccer match in nearby Piraeus when the assailant got into a quarrel with the hip-hop singer about soccer.

The discussion eventually strayed into politics.

The attacker left the cafe, but soon returned - with some Black Shirts in tow - and accosted Fryssas, stabbing him in the chest.

Golden Dawn denied any responsibility for the fatal incident.
