A US appeals court has rejected to reinstate Trump travel ban on visitors from seven mainly Muslim countries.
The 9th US Circuit Court of Appeals said it would not block a lower-court ruling that halted the order.
As expected, Mr Trump responded with an angry tweet saying national security was at risk and there would be a legal challenge.
SEE YOU IN COURT, THE SECURITY OF OUR NATION IS AT STAKE!

But in a unanimous ruling, the court said the government had not proved the terror threat justified the ban.
“The government has pointed to no evidence that any alien from any of the countries named in the Order has perpetrated a terrorist attack in the United States,” it said.
It also rejected the argument that the president had sole discretion to set immigration policy. “Rather than present evidence to explain the need for the executive order, the government has taken the position that we must not review its decision at all,” said the ruling. “We disagree, as explained above.”
