What’s going on with the demonstrations at New York’s JFK Airport?

It was to protest Trump’s restrictions on refugee entry.

After two Iraqis holding entry visas were detained at New York's JFK Airport, a demonstration took place at JFK Airport on the 28th local time, with more than 100 people demonstrating. Demonstrators chanted slogans such as "No hatred, no fear, immigrants are welcome here" and "No ban, no wall" to protest Trump's executive order restricting the entry of refugees from seven countries.

On the same day, one of the detained Iraqis was released. The released Iraqi had served as a translator for the US military in Iraq for the past ten years, while the other Iraqi was still in custody.

In addition, on the same day, at Cairo Airport in Egypt, several refugees were refused boarding a plane bound for JFK Airport.
