Ukrainian officials said Melania Trump played a pivotal role in organising the six-day ceasefire to evacuate civilians from the Russian-occupied southern Ukrainian town of Oleshky, which began on Tuesday and concluded on Sunday, in what was the longest local pause in fighting since Russia's full-scale invasion in 2022.

Previous attempts to pause the fighting have either failed to take hold or quickly unravelled.

Nearly 800 people were evacuated, Melania Trump said.

The plight of the city in Ukraine's Kherson region caught the attention of the US first lady, and the White House said she brokered the humanitarian mission.

Pope Leo XIV also spoke this month with Zelensky and Vladimir Putin, urging them to allow humanitarian aid into Oleshky and the safe evacuation of civilians, the Vatican said.

Zelensky previously said he was grateful to Melania Trump for her role in halting the fighting in and around Oleshky.

“We are grateful that they are organising this possibility to evacuate people,” he said.

Russia’s ombudsperson Yana Lantratova said: “Her personal involvement is of great importance to the entire process.”

Both sides are eager to win US President Donald Trump’s approval as he pushes for an elusive peace settlement.
