The proposed development centers on Sazan, an uninhabited former military island, and has also drawn scrutiny over related plans near the Vjosa-Narta wetlands, an ecologically sensitive area used by migratory birds and other protected species. Albania’s Special Anti-Corruption Prosecution Office (SPAK) said Tuesday it had opened an investigation into changes to the area’s protected status and land ownership that paved the way for potential tourism development, including the Sazan project. Prime Minister Edi Rama invited protesters to form a delegation for talks, but organizers rejected the offer and called another demonstration for Wednesday.
