What do we know about the ceasefire talks?

Russia and Ukraine will meet in Istanbul for the latest ceasefire talks, which will take place at the same venue where previous negotiations in May and June failed to yield a ceasefire, the Agence France-Presse news agency reported.

“There is a lot of work to be done before we can talk about the possibility of some top-level meetings,” he said.

“The agenda from our side is clear: the return of prisoners of war, the return of children abducted by Russia, and the preparation of a leaders’ meeting,” he said.

What happened last time?

The Russian memorandum, which was published by the Interfax news agency, said a settlement of the war would require international recognition of Crimea — a peninsula annexed by Russia in 2014 — and four other regions of Ukraine that Russia has claimed as its own territory. Ukraine would have to withdraw its forces from all of them.
