Trump's social media post came after he announced that a US National Guard member had died after a shooting in Washington DC - for which an Afghan national has been blamed. He did not give further details or name which countries might be affected. Such a plan could face legal challenges and has already prompted pushback from UN agencies. The president's announcements after Wednesday's fatal attack represent a further toughening of his stance towards migrants during his second presidency.

Among other moves, Trump has sought to enact mass deportations of migrants who entered the US illegally, to drastically cut the annual number of refugee admissions, and to end automatic citizenship rights that currently apply to nearly anyone born on US territory. (BBC)
