The number of countries whose citizens face a full or partial travel ban on entry to the United States increased from 19 to 39.

US President Donald Trump signed a proclamation to expand US travel restrictions, adding 20 more countries and the Palestinian Authority to the list.

Other countries newly subjected to the full travel ban came from some of Africa's poorest countries -- Burkina Faso, Mali, Niger, Sierra Leone and South Sudan -- as well as Laos in southeast Asia.
