Anti-austerity demonstrators were on Thursday staging a sitin protest at the office of Greece's finance ministry general secretary, local media reports said.
The demonstrators, described as members of SYRIZA's youth organization, were protesting controversial comments made by Giorgos Mergos earlier this week.
On Tuesday Mergos suggested that Greece's basic salary was too high. He later said his comments were misinterpreted.
“The only answer to those who are planning to impose new measures designed to impoverish workers and young people is collective and defiant struggles to overturn the government and the memorandums,” the protesters said in a statement.
Riot police have been sent to the scene, the reports said.
Finance Minister Yannis Stournaras on Wednesday insisted that there are no plans to reduce the minimum wage, as SYRIZA suggested that the government has already agreed to bring it down from 586 euros next year.
