It’s all over the world. Donald Trump Executive order may have been halted or annulled by US superior courts but it isn’t over yet. Donald Trump travel ban orders is attracting protesters from all over the world.

From London and Paris to New York and Washington, thousands of people took to the streets Saturday in American and European cities to protest United States President Donald Trump's travel ban amid a fierce legal battle over the order.

The biggest demonstration by far took place in the British capital, where an estimated 10,000 people turned out, chanting "Theresa May: Shame on You" to denounce the British prime minister's support for the new US leader.

Brandishing placards declaring "No to scapegoating Muslims" and "Socialism not Trumpism," the protesters moved from the US embassy toward May's Downing Street office.

In an executive order issued on Jan 27, Trump slapped a blanket ban on nationals of seven mainly Muslim countries ─ Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen ─ barring their entry to the United States for 90 days.

Refugees were also barred from entry for 120 days, except those from Syria, who were blocked indefinitely.

On Friday, a US federal judge suspended the ban, a move which the Republican president ─ who took office on Jan 20 ─ condemned and vowed to fight.

Late Saturday, the Justice Department filed its motion to appeal the judge's order, though the legal brief detailing its arguments has yet to come.

"We'll win. For the safety of the country, we'll win," Trump told reporters.
