Ukraine and Russia are both major global suppliers of wheat, barley, sunflower oil, and other affordable food products that developing nations depend on.

They must cope with soaring production and transportation costs caused by Russia’s blockade of many Black Sea ports and recent restrictions that neighboring countries imposed on Ukrainian grain.

The White House says it now estimates that just since December Russia has suffered 100,000 casualties as Ukraine has rebuffed a heavy assault in eastern Ukraine.

Almost all of the 23 victims of the attack on Friday died when two missiles slammed into an apartment building in Uman.

The incident comes a day after Russia fired more than 20 cruise missiles and two drones at Ukraine, killing at least 23 people.
