Oil import ban 

The U.S. is expected to impose a ban on Russian oil import, Democratic U.S. Senator Chris Coons said. In an interview with CNN, Coons said the announcement of the ban could come on Tuesday or Wednesday. 

Russia is the world's biggest exporter of oil and natural gas. Moscow is subject to global financial sanctions over the war, but its energy exports have been exempted until now.

The British government is expected to make a similar announcement later on Tuesday, banning imports of Russian oil but not gas, Politico reported. The publication said there would be a months-long lead-in time on the ban to allow the global market to adjust and to stop people panic-buying petrol.

UK Prime Minister Boris Johnson said Monday, that the world could not simply stop using oil and gas from Russia but could accelerate the transition away from it.

Russian Deputy Prime Minister Alexander Novak warned Monday that Moscow could cut Europe's gas supplies in response to sanctions and said any ban by Western allies on Russian oil imports would have "catastrophic consequences."

The economic impact of the war is already having an effect, fuelling concerns it could derail global economic recovery from the coronavirus pandemic.

U.S. gasoline pump prices hit a record high, London trade in industrial metal nickel had to be suspended after prices more than doubled in a matter of hours, and Britain's energy giant Shell is pausing spot purchases of Russian oil, apologizing for buying a shipment last week.

Humanitarian corridors

Russia opened a humanitarian corridor on Tuesday, letting Ukrainians flee the eastern city of Sumy, but Kyiv accused Moscow of shelling a similar route intended to allow residents to escape the besieged southern port of Mariupol.

"Ceasefire violated! Russian forces are now shelling the humanitarian corridor from Zaporizhzhia to Mariupol," Ukraine's foreign ministry spokesperson Oleg Nikolenko posted on Twitter.

"Eight trucks + 30 buses ready to deliver humanitarian aid to Mariupol and to evac civilians to Zaporizhzhia. Pressure on Russia MUST step up to make it uphold its commitments."

The Interfax news agency said Moscow was also opening humanitarian corridors for the cities of Chernihiv, Kharkiv, and the capital Kyiv. 

Russia's defense ministry said that Ukrainian authorities only confirmed one evacuation route for civilians, from Sumy through Poltava to the Polish border, out of 10 proposed. 

Earlier attempts to evacuate residents from Mariupol failed on Saturday and Sunday, with each side accusing the other of continuing to fire.

The International Committee of the Red Cross (ICRC) said Mariupol residents faced "atrocious" conditions and were running out of food, water, and medical supplies.

"The bottom line today is that this situation is really apocalyptic for people," ICRC head of media Ewan Watson said in Geneva.

Two million refugees

The United Nations said the number of refugees who have fled Ukraine had surged past 2 million, describing the flight as one of the fastest exoduses in modern times.

At the Medyka border crossing, east of Przemysl in Poland, where refugees arrived by foot and by car, a line of waiting vehicles stretched about 6 kilometers with waiting times on the Ukrainian side running at 20 hours, two women told Reuters after they made it across.

The onslaught has created a huge refugee crisis for European countries that have taken in Ukrainians fleeing the conflict, particularly Poland.

"It doesn't stop," Filippo Grandi, the UN High Commissioner for Refugees, said.
