As fighting rages on in Ukraine, hundreds of thousands are seeking refuge in a number of neighbouring countries. On Feb. 28, the head of a UN agency said that more than 500,000 people have fled since the start of the Russian invasion. Cars have lined up for more than 10 kilometres at certain checkpoints, while others have had no choice but to walk – sometimes, for 50 km – to escape.Moldova is one such country accepting refugees. According to the Moldovan Border Police, 70,000 people from Ukraine have entered the country since the start of the conflict. International correspondent Nathan Vanderklippe reports from that tiny, landlocked country about the people fleeing Ukraine and how bordering countries are responding to the crisis.
