headlines: Russia-Ukraine war: what we know on day 121 of the invasion
articles: The last Ukrainian forces fighting in the heavily contested eastern city of Sievierodonetsk have been ordered to withdraw in order to avoid being encircled, as fears grow that the neighbouring city of Lysychansk could also fall to Russia within days. The anticipated loss of Sievierodonetsk is the latest battlefield reverse for Kyiv after its defeat in the port city of Mariupol. According to some estimates about 12,000 civilians remain in Sievierodonetsk, out of a prewar population of 160,000. All three bridges offering escape routes west over the Siverskyi Donets River to the twin city of Lysychansk have been destroyed in fighting, and the mayor, Oleksandr Striuk, says the humanitarian situation is critical.
