 Russia says it has seized Ukraine's southern city of Kurson, but the claim has not been confirmed. The United Nations refugee agency says more than one million people have fled Ukraine since the start of Russia's invasion of the country last week. In Taiwan, power is slowly returning after a problem at a main production center left five million people, mainly in the south, without electricity. And in Sudan, exports dropped 85% in January, partly because of international sanctions ordered against the country's military rulers.
