Some countries targeted under a new US travel ban passed by President Donald Trump have attacked the move, along with the United Nations.
On Monday, President Trump signed a new executive order placing a 90-day ban on people from six mainly Muslim nations.
The order was presented as a means to strengthen US national security against terror threats.
On Tuesday however, two of the countries, Sudan and Somalia, said the move was unjustified.
The directive, which includes a 120-day ban on all refugees, takes effect on 16 March.
It follows a previous order, which was blocked by a federal court, that sparked confusion at airports and mass protests.
