Portugal Colonial - Zelensky says Russian ceasefire memorandum is an 'ultimatum'

His comments came after Russian and Ukrainian delegations in Istanbul swapped terms for agreeing to a ceasefire and said they were ready to host another round of prisoner exchanges.

Zelensky told reporters -- including from AFP -- that the Russian document outlining Moscow's requirements to halt its invasion amounted to an ultimatum.

"That is, it is not a memorandum of understanding. At least a memorandum of understanding should be signed by two parties, not just one party demanding something," he said sitting around a table with international and Ukrainian media.

"Therefore, it cannot be called a memorandum. It is, after all, an ultimatum from the Russian side to us," he added.

Zelensky said that there was no point in continuing peace talks in Istanbul with the current level of Russian delegates as they are not high-ranking enough, calling instead for a sit-down with Putin.

"We are ready for exchanges, but to continue diplomatic meetings in Istanbul at a level that does not solve anything further, I think, is pointless," Zelensky said, referring to the two agreements for prisoner of war swaps that have come out of the talks.

He said instead that he was ready to hold a meeting with Putin and Trump.

"We are ready for such a meeting any day," Zelensky said, adding that he was proposing that a ceasefire be put in place before any such summit, which would also include Turkish President Recep Tayip Erdogan.

The White House said that Trump was "open" to meeting his Russian and Ukrainian counterparts in Turkey after the two sides failed on Monday to make headway towards an elusive ceasefire.

Zelensky added that Ukraine and Russia were prepared to exchange captured military personnel this weekend, following the agreement between Moscow and Kyiv brokered in Turkey this week.

"The Russian side has passed on information that this weekend -- on Saturday and Sunday -- they will be able to transfer 500 people, 500 of our military," Zelensky said.

"We will be ready to exchange the relevant number" of prisoners of war, he added.

Tens of thousands have been killed since Russia launched its full-scale invasion of Ukraine, with swathes of eastern and southern Ukraine destroyed and millions forced to flee their homes in Europe's largest refugee crisis since World War II.
