New York: Tens of thousands of people rallied in USinfo-icon cities and at airports on Sunday to voice outrage over President Donald Trumpinfo-icon's executive order restricting entry into the country for travelers from seven Musliminfo-icon-majority nations.

In New York, Washington and Boston, a second wave of demonstrations followed spontaneous rallies that broke out at US airports on Saturday as US Customs and Border Protection agents began enforcing Trump's directive. The protests spread westward as the day progressed.

"The protests are cascading across Americainfo-icon. Inside airport arrival halls, in city centres, outside the White House, and beside mosques the crowds are gathering", ITV channel reported.

It is an impressive and largely spontaneous display of popular resistance, the report said and quoting activists said they (protestors) are clinging to the original purpose of America, as a sanctuary for the persecuted and as a destination for the forlorn, the report said.

"These demonstrations feel less concerned with a particular presidential executive order than with saving the soul of the country".

The order, which bars admission of Syrian refugees and suspends travelinfo-icon to the United Statesinfo-icon from Syriainfo-icon, Iraqinfo-icon, Iraninfo-icon and four other countries on national security grounds, has led to the detention or deportation of hundreds of people arriving at US airports.

One of the largest of Sunday's protests took place at Battery Park in lower Manhattan, within sight of the Statue of Liberty in New York Harbor, long a symbol of welcome to US shores.

Democratic Senator Charles Schumer of New York told the crowd that Trump's order was un-American and ran counter to the country's core values. "What we are talking about here is life and death for so many people," the Senate Democratic leader said. "I will not rest until these horrible orders are repealed."

The march, estimated to have grown to about 10,000 people, later began heading to the US Customs and Border Protection office in lower Manhattan.

In Washington, thousands rallied at Lafayette Square across from the White House, chanting: "No hate, no fear, refugees are welcome here." It was the second straight weekend that Washington was the scene of protests. Last Saturday, hundreds of thousands of women participated in an anti-Trump rally and march, one of dozens staged across the country.

On Sunday, many of the protesters left the White House area and marched along Pennsylvania Avenue, stopping at the Trump International Hotel where they shouted: "Shame, shame, shame."

A crowd that police estimated at 8,000 people eventually arrived at the steps of the US Capitol, where a line of uniformed officers stood guard. As the crowd passed the Canadian Embassy en route to the Capitol, protesters chanted: "Hey hey, ho ho, I wish our leader was Trudeau." It was a reference to Canadian Prime Minister Justin Trudeau's Saturday Twitterinfo-icon message affirming his country's welcoming policy toward refugees.

Trump defended the executive order in a statement on Sunday, saying the United States would resume issuing visas to all countries once secure policies were put in place over the next 90 days.

"To be clear, this is not a Muslim ban, as the mediainfo-icon is falsely reporting," Trump said. "This is not about religioninfo-icon - this is about terror and keeping our country safe."

Jennifer Fagen, 47, a sociology professor at Lamar University in Beaumont, Texas, said she hoped she did not lose her job for protesting. "I'm Jewish, and it's supposed to be 'never again,'"

Fagen said, referring to the Holocaust. "Jews should be the first ones to defend Muslims, considering what has happened to us, and it seems it's being repeated under Trump."

At Detroit Metropolitan Airport, police cordoned off sections of terminal as up to 3,000 demonstrators chanted, "No hate, no fear, refugees are welcome here." Among the demonstrators were Wail Aljirafi and his wife, Samyeh Zindani of Ann Arbor, Michigan, and their three children. "We want them to feel that they're always included," Zindani, a Yemeni-American, told Reuters news agency.
