Muslim immigrants held prayers at Denver International Airport as protesters helped create a protective circle so they could pray in peace.

Protesters gathered at DIA to protest Trump’s executive order banning citizens and immigrants of 7 Muslim-majority countries from entering the United States.

There were also other rallies held at airports across the U.S. on Saturday, including international hubs in New York, Chicago and D.C., where immigrants and refugees were detained. More protests are scheduled for Sunday, CNN reported.

U.S. President Donald Trump has issued an order imposing a 90-day ban on entry from citizens of Iran, Iraq, Syria, Yemen, Sudan, Libya and Somalia.

According to Amal Kassir who organized the event, the purpose of the demonstration was to welcome her Muslim friend Omar, who happened to be flying into DIA from the East Coast. The protesters were holding signs that read “Welcome Omar” on one side and have the First Amendment on the other side.

“We are so non-political that we are constitutional,” she said, describing the event as “a demonstration of welcome” that stands openly against Donald Trump’s order.

“We are only dressed in red, white and blue today. This is for America. It’s not for anyone else. It’s not for Muslims, it’s not for refugees. It’s not for anybody but America.”
