Refugees have continued to stream into Moldova, prompting the country's leader to call for international assistance to cope with the influx.
“We now have over 270,000 people who have crossed the border," Moldova Prime MInister Natalia Gavrilița has told the BBC World Service.
"More than 100,000 people who have chosen to stay – at least temporarily. For a country like Moldova these are quite high numbers. “
Moldova, a small country of about 2.5 million sandwiched between Ukraine and Romania, is one of Europe's most economically fragile. The number of Ukrainian refugees represent about a 4% increase in their population.
Ms Gavrilița added that Moldovan civilians are helping to house and care for the refugees that are arriving by the thousands every day.
“We are very worried about the economic consequences of the war... which is hitting particularly hard a country like Moldova, one of the poorest in Europe," she said.
"We certainly need outside help.”
