Protests have erupted in Bulgaria following the arrest of a liberal, pro-EU mayor, with demonstrators alleging political interference in the justice system. The arrest has fueled concerns about corruption within the Balkan nation, with some critics suggesting the European Union is overlooking these issues due to strategic considerations. The protests highlight growing tensions between those advocating for closer ties with the EU and those wary of external influence on Bulgarian affairs. The situation is being closely monitored by international observers concerned about the rule of law and democratic principles in the region.
