MINSK (Reuters) - Talks between leaders of France, Germany, Russia and Ukraine on the Ukraine crisis in Minsk, Belarus, could continue for at least another five to six hours, a Ukrainian presidential aide said early on Thursday.
"We've got another 5-6 hours of work. At least. But we should not leave here without an agreement on an unconditional ceasefire. There's a battle of nerves underway," aide Valeriy Chaly said in a Facebook post.
Chaly made his comment after talks had already been underway for seven hours.
