June 4 (UPI) -- Thousands of Albanians marched in the capital Tirana for a third day straight to protest against a $1.6 billion luxury resort backed by Donald Trump's son-in-law, Jared Kushner, in a national marine park off the country's Adriatic Sea coast.

Some demonstrators in Wednesday's protest held inflatable flamingos aloft to highlight the impact they fear the project will have in and around Sazan Island, where work recently got underway in the midst of one of the Mediterranean's most environmentally-vulnerable areas.

Scuffles broke out with police who fired water canon at protesters.

An offer to meet with opponents from Prime Minister Edi Rama, who has staked his premiership on what he has billed as a developmental coup for the former communist state, was rejected as calls for the project to be halted grew, with protests also set to spread to the south of the country.
