European leaders are openly denouncing President Donald Trump’s executive order banning travel from seven Muslim majority nations.

German Chancellor Angela Merkel told Trump that the global fight against terrorism was not an excuse for his ban, Reuters reported her spokesman as saying.

“She is convinced that even the necessary, decisive battle against terrorism does not justify putting people of a specific background or faith under general suspicion,” Merkel spokesman Steffen Seibert said.

In a phone call with Trump on Saturday, Merkel also told him that the Geneva Conventions required the international community to take in refugees on humanitarian grounds, Seibert said.

Trump frequently criticized Merkel throughout the presidential campaign for her decision to accept refugees.

In the United Kingdom, a petition citing Trump’s “well-documented misogyny and vulgarity” and calling for the cancellation of a state visit by Trump has reached more than 1 million signatures. 

According The Independent, the petition said Trump, whose mother emigrated from Scotland, should be allowed into the country but not allowed to meet Queen Elizabeth II.

British Prime Minister Theresa May was initially silent on the ban but was forced to take a stand after a cross-party backlash and calls for an emergency debate.

May, who was the first foreign leader to meet with Trump at the White House, later issued a statement saying she did “not agree” with Trump’s order. 

The U.K. government and others were scrambling Monday to determine that status of their citizens with dual citizenship in the seven countries included in Trump’s ban.

Outgoing French President Francois Hollande didn’t directly address the ban or Trump but expressed concern about Trump’s policies since taking office 10 days ago.

“What is at stake is populism,” Hollande said at a meeting of southern European Union countries in Lisbon, Portugal, according to The Guardian. “The kind of discourse now coming from the United States encourages populism and even extremism.”
