The European Union has expressed concern following incidents of violence, including the use of Molotov cocktails, during the fifth national protest organized by Albania’s opposition in the capital on Saturday.

In a statement issued through the office of the Delegation of the European Union to Albania just hours after the demonstration, political actors were urged to exercise restraint.

“We support constructive engagement in advancing important reforms on Albania’s path toward the European Union,” the statement said.

The EU Delegation emphasized that the right to peaceful assembly is a fundamental pillar of any democratic society, but stressed that it must be exercised responsibly, with full respect for the rule of law and the safety of all individuals.

The delegation also voiced concern over recent acts of violence in Tirana that it said endangered lives.

According to police, four protesters have been arrested in connection with Saturday’s unrest. They are suspected of assaulting officers on duty, disturbing public order, violating rules related to explosive materials, and destroying property by fire.

Authorities confirmed that one of the damaged sites included the so-called “Villa 31,” the former residence of communist-era dictator Enver Hoxha. Police reported that flammable materials were thrown toward the building while foreign nationals were inside, placing them at risk.
