The Russian president, Vladimir Putin, has said war with neighbouring Ukraine is "unlikely", in an interview for Russian television. Mr Putin also stressed his support for the Minsk agreement as the best way to stabilise eastern Ukraine. On the ground, Ukraine has delayed the promised withdrawal of heavy weapons from the frontline, blaming separatist rebels for continued violations of the ceasefire. Rebel leaders, who have yet to pull back their heavy weapons, have made similar accusations. Our correspondent, Paul Adams, reports from the self-declared People's Republic of Donetsk, where an old Soviet holiday is being marked.
