MOSCOW, Nov 26 (AFP) - Vladimir Putin told the mothers of Russian soldiers serving in the war that he "shares the pain" of those who lost their sons and told them not to believe "lies" about the invasion of Ukraine.

"I want you to know that I, personally, all the leaders of the country, share this pain. We know that nothing can replace the loss of a son," said Putin.

He added that Mother's Day, celebrated in Russia on Sunday, would be marked this year by "a feeling of anxiety and concern" among the women concerned, whose "thoughts will be with their boys".

The meeting took place in Putin's residence in Novo-Ogarevo, near Moscow, and was the first of its kind since the Russian invasion started on 24 February. The Kremlin rarely refers to losses suffered in Ukraine, and Friday's event came after weeks of criticism posted on social networks by relatives of men mobilised in early autumn.

Olga Tsukanova, the founder of Russia's Council of Mothers and Wives, has accused Putin of excluding the organisation from Friday's meeting.

In a recorded video address, Tsukanova demanded that the president should meet with "real mothers" of those who serve in the country's army as opposed to the women "hand-picked" by authorities for the event.

Many wives and mothers of men drafted into the army have accused the authorities of failing to adequately train or equip their relatives before sending them to the front.
