The EU on Thursday agreed to approve temporary protection for refugees fleeing the war in Ukraine -- so far numbered at one million -- while also setting up a humanitarian hub in Romania.
The moves by the European Union came in parallel to its sanctions on Russia imposed in successive waves over the course of the invasion, now in its eighth day.
In Washington, the administration of President Joe Biden announced a similar move, granting temporary protected status to Ukrainians already in the country.
That means they can remain in the US and the threat of deportation is lifted.
British Prime Minister Boris Johnson and Brazilian President Jair Bolsonaro have called for a ceasefire in Ukraine, a Johnson spokesperson said following talks between the two leaders.
"The leaders agreed on the requirement for an urgent ceasefire in Ukraine and said peace had to prevail," the Downing Street spokesperson said.
Johnson said the "world could not allow President Putin's aggression to succeed," denouncing his regime's "disgusting actions" that killed civilians and destroyed cities.
