People gathered at major airports across the U.S. over the weekend to protest U.S. President Donald Trump's executive order targeting refugees and travellers from Muslim-majority countries.

The president barred all Syrian refugees from entering the U.S. for an unstated amount of time, banned all refugees worldwide for at least four months and issued a 90-day ban on travellers from Yemen, Syria, Sudan, Somalia, Iraq, Libya and Iran. 

Thousands of Americans protested at airports, already the sites of chaos and confusion as authorities worked to interpret the ever-fluctuating orders from the Trump administration, and thousands more spilled out into city streets.

New York 

One of the biggest protests was at New York's John F. Kennedy Airport, where thousands spontaneously gathered Saturday to demand the release of detained travellers. A court win by the American Civil Liberties Union has temporarily prevented authorities from deporting the 100 to 200 people who were being held at U.S. airports.

Protesters in the city are also starting to stream into New York City's Battery Park. The big crowd gathered Sunday near the ferries that carry tourists to the Statue of Liberty and Ellis Island, the place where 12 million people entered the United States in the golden age of immigration.

Washington

More than 100 protesters and dozens of immigration attorneys have gathered at the international arrivals terminal at Dulles International Airport outside Washington, D.C., cheering people arriving from Muslim countries.

The crowd chanted "No ban, no wall" and other slogans, and at one point sang The Star-Spangled Banner.

One woman brought pizza for the protesters.
