Russia’s Defence Ministry said shelling towards the Ukrainian city of Kherson stopped at 4am Moscow time (0100 GMT) to prepare for the humanitarian operation.
Dmytro Lubinets, Ukraine’s parliament commissioner for human rights, confirmed the ceasefire in a Facebook post, stating that Kyiv was fulfilling its commitments under the arrangement.
The agreement aims to deliver essential supplies and evacuate residents facing severe shortages of food and medicine in the frontline town.
Oleshky lies on the eastern bank of the Dnipro River in Ukraine’s southern Kherson region, opposite the city of Kherson, which remains under Ukrainian control. Russian forces captured the town during the early days of their February 2022 invasion.
The White House said last week that US First Lady Melania Trump had helped secure the ceasefire.
Meanwhile, Russian attacks continued elsewhere in Ukraine. A missile strike on Kyiv on Monday killed at least one person and injured 10 others. Further explosions were reported in the capital on Tuesday morning.
