Sit down: A demonstration against Donald Trump's executive order on immigration at Seattle-Tacoma International Airport. Credit:AP Merkel's sentiments were echoed in Paris and London; "Terrorism knows no nationality. Discrimination is no response," said French Foreign minister Jean-Marc Ayrault, while his British counterpart Boris Johnson tweeted: "Divisive and wrong to stigmatise because of nationality." Along with Syria, the US ban of at least 90 days affects travellers with passports from Iran, Iraq, Libya, Somalia, Sudan, and Yemen, including those with dual nationality that includes one of those countries. Partial reversal? A top White House official appeared to reverse a key part of President Donald Trump's immigration order on Sunday, saying that people from the affected countries who hold green cards will not be prevented from returning to the United States.

But the official, Reince Priebus, the White House chief of staff, also said that border agents had "discretionary authority" to detain and question suspicious travellers from certain countries. That statement seemed to add to the uncertainty over how the executive order will be interpreted and enforced in the days ahead.

In a Twitter post Sunday morning, Trump deplored the killings of Christians in the Middle East without noting the killings of Muslims, who have been killed in vastly greater numbers in Iraq, Syria and elsewhere. Allies silent Trump said his order, which indefinitely bans refugees from Syria, was "not a Muslim ban", though he added he would seek to prioritise Christian refugees fleeing the country.

Boris Johnson described the immigration order as "divisive and wrong". Credit:Bloomberg Washington's Arab allies, including the Gulf states and Egypt, were mostly silent. The government in Iraq, which is allied with Washington in the battle against ultra-hardline Islamist group Islamic State and hosts over 5000 US troops, also did not comment on the executive order. Canada's Prime Minister Justin Trudeau said his country would welcome those fleeing war and persecution.

Iran vows to respond In Baghdad, influential Shi'ite cleric Moqtada al-Sadr said American nationals should leave Iraq, in retaliation for the travel curbs.

There was no immediate reaction to the curbs from Islamic State, although in the past it has used US monitoring of Muslim foreigners to stoke Muslim anger against Washington.

"Unlike the US, our decision is not retroactive. All with valid Iranian visa will be gladly welcomed," Zarif said. Authorities in Sudan, which is also targeted by the ban, summoned the US charge d'affaires in Khartoum. They said the order sent a "negative message", coming two weeks after Washington announced it would ease economic sanctions on the country. Trump's executive order on Friday took effect immediately, wreaking havoc and confusion for would-be travellers with passports from the seven countries and plunging America's immigration system into chaos.

The Department of Homeland Security said about 375 travellers had been affected by the order, 109 of whom were in transit and were denied entry to the United States. Another 173 were stopped by airlines before boarding. Fuad Sharef, his wife and three children were among the first victims. They had waited two years for a visa to settle in the United States, selling their home and quitting jobs and schools in Iraq before setting off for a new life they saw as a reward for working with US organisations. They were prevented from boarding their connecting flight to New York from Cairo airport on Saturday, detained overnight and forced to board a flight back to northern Iraq. 'I am totally broken' "We were treated like drug dealers, escorted by deportation officers," Sharef told Reuters, likening Trump's decision to the dictatorship of former Iraqi leader Saddam Hussein. "I am broken, I am totally broken."

A 32-year-old Syrian man, Nail Zain, was among dozens of people at Istanbul's Ataturk Airport prevented from flying to the United States on Sunday. He told Reuters he was supposed to fly to Los Angeles, but officials said his visa was cancelled. "My wife and my son are in the United States. My son has American nationality. And we have been waiting for this moment for two years. Finally when I got the chance, they prevented me as a Syrian passport holder from travelling," he said. He was later taken out of the terminal by authorities. Trump, a businessman who successfully tapped into American fears about militant attacks during his campaign, had promised what he called "extreme vetting" of immigrants and refugees from areas the White House said the US Congress deemed high risk. He said on Saturday of his order: "It's working out very nicely. You see it at the airports, you see it all over."

The travel curbs, however, also drew criticism from several other countries around the globe. In Jakarta, Indonesian Foreign Minister Retno Marsudi said the Muslim-majority nation deeply regretted Trump's plans for "extreme vetting" of people from some Muslim countries. Italian Prime Minister Paolo Gentiloni said "open society, plural identity, no discrimination" were the "pillars of Europe", while the Danish, Swedish and Norwegian governments also registered their opposition. Danish foreign minister Anders Samuelsen tweeted: "The US decision not to allow entry of people from certain countries is NOT fair." Canadian Prime Minister Justin Trudeau said his country welcomed those fleeing war and persecution, even as Canadian airlines said they would turn back US-bound passengers to comply with an immigration ban on people from seven Muslim-majority countries.
