Police in Albania clashed with protesters Tuesday in the capital, Tirana, as demonstrations against a luxury coastal development linked to U.S. President Donald Trump’s son-in-law, Jared Kushner, reached their 100th day.

Protesters challenged a police cordon in the center of Tirana as they attempted to reach parliament, pelting officers in riot gear with eggs and tomatoes. The marches occurred as parliament resumed from its summer recess.

The protests, dubbed the “flamingo revolution” due to signs depicting the bird that could be harmed by the development, aim to halt a massive coastal project that critics argue would cause environmental damage and restrict public access to the shoreline.

Initially focused on the development, the nightly protests in Tirana have evolved into a significant challenge to Albania's long-governing Socialist government. Prime Minister Edi Rama, a target of the demonstrations, supports the investment, stating it will help modernize the country after decades of Communist isolation.

During the clashes, demonstrators chanted “Arrest Rama!” as police escorted lawmakers to and from the parliament building. Several protesters were detained, though the number of arrests was not immediately clear.
