According to CNN, the UN and its partners have provided food to hundreds of thousands of people, but the security situation has made it difficult to reach certain areas. The statement comes as both sides lobbed accusations at each other of preventing civilians from safely leaving.

Meanwhile, Russia has declared a ceasefire in four cities in Ukraine from 10 am this morning and announced that it would open humanitarian corridors for civilian evacuations. But there are reports that Ukraine has rejected this as the corridors all lead to Russia or its partner, Belarus.
