Ukraine declares state of emergency

Ukraine's foreign minister has made a desperate appeal for help at the UN General Assembly, saying failure to halt Russian aggression would mark the end of the current world order. A young Ukrainian woman living in Russia tells us what she makes of Kyiv ordering all Ukrainians to leave for their safety. And a senior humanitarian official explains what war could mean for those who live in Ukraine.
