Thousands of people demonstrated in Albania’s capital, Tirana, on Wednesday against a luxury resort project linked to Jared Kushner, the son-in-law of U.S. President Donald Trump. Protesters gathered outside Prime Minister Edi Rama’s office, carrying placards reading “Albania is not for sale,” and their march extended about half a mile along one of the city’s main roads.

The planned $5.8 billion resort, to be built in the southern coastal village of Zvërnec, has sparked widespread anger because of its proximity to a protected wetland that serves as a nesting and resting site for flamingos, seals, and sea turtles. Critics have also raised concerns about a lack of transparency surrounding the project.

The protest, dubbed the “Flamingo Revolution,” originated in Zvërnec, where the resort is planned. Demonstrators said the project reflects long-standing issues in Albania’s governance and environmental protection.
