ATHENS, Nov. 16 (Xinhua) -- A Greek anti-establishment group calling itself "Revolutionary Self-Defense" claimed on Thursday responsibility for an armed attack against the headquarters of the opposition socialist PASOK party in central Athens ten days ago.
In a statement posted on an anti-establishment website, the group assumed responsibility for opening fire against a police van parked outside the building, as well as a similar attack against the same target in January and the Mexican Embassy in Athens in the summer of 2016.
No injuries occurred during the November 6 attack, as well as the attack on the embassy, while one officer was slightly injured in January.
The assailants fled the site and have not been arrested yet.
The headquarters of PASOK, which ruled Greece for several years since 1981, have been targeted numerous times in recent years by anarchists, who have been operating in the nearby Exarchia area for decades, most often with petrol bombs.
Opposition parties have called on the government to take more measures to address the issue, expressing concern for violent incidents also during Friday's anniversary of the student uprising against military dictatorship (1967-1974).
Members of an anti-establishment group have occupied from Tuesday the nearby National Polytechnic school premises where the uprising started in 1973, and police forces have been deployed in the area.
From the Polytechnic school starts each year a march to commemorate the victims which is organized by student unions and political parties. The demonstration is often marred by clashes between hooded anarchists and police.
