Ukraine war: Russia says 'liberation' of Donbas its key priority

The "liberation" of eastern Ukraine's Donbas region is an "unconditional priority" for Russia, Foreign Minister Sergei Lavrov has said in an interview.

Defending Russia's ongoing military operation more than three months after it invaded, he said again it was aimed at "demilitarising" its neighbour.

He repeated the Kremlin's widely ridiculed line that Russia is fighting a "neo-Nazi regime".

And he denied speculation that Russian President Vladimir Putin was ill.

The man who has dominated Russia for more than two decades turns 70 in October.

Noting that President Putin regularly appeared in public, Mr Lavrov told TF1: "I don't think that sane people can see in this person signs of some kind of illness or ailment."

Asked about the human cost of the fighting, which has seen devastating artillery and rocket attacks on some urban areas, he insisted Russian soldiers were "under strict orders categorically to avoid attacks and strikes on civilian infrastructure".

The fighting is now focused Donbas - the mining belt made up of the Donetsk and Luhansk regions. Separatists in the two regions, which historically have strong ties to Russia, broke away in 2014 and are now fighting alongside Russian troops to take full control.

Mr Lavrov told TF1 that winning in "the Donetsk and Luhansk regions, recognised by the Russian Federation as independent states, is an unconditional priority".

However, he added, it was up to the rest of Ukraine if people there were "happy to return to the authority of a neo-Nazi regime that has proven it is Russophobic in essence".

Russia has already been forced to pull back from an attempt to overrun the capital Kyiv, after been repelled by Ukrainian forces.

Speaking in the city, he said his soldiers would defend their land "to the last man". "They [the Russians] have no chance," he said. "We will fight and we will definitely win."
