Russia-Ukraine peace talks resume; Kyiv denies hitting fuel oil depot on Russian soil

Peace talks between Russia and Ukraine resumed on Friday after Ukrainians denied launching a helicopter attack on a fuel depot on Russian soil.

Talks to stop the fighting in Ukraine resumed Friday, as another desperate attempt to rescue civilians from the encircled city of Mariupol failed and the Kremlin accused the Ukrainians of launching a helicopter attack on a fuel depot on Russian soil.

Ukraine denied responsibility for the fiery blast, but if Moscow's claim is confirmed, it would be the war's first known attack in which Ukrainian aircraft penetrated Russian airspace.

“Certainly, this is not something that can be perceived as creating comfortable conditions for the continuation of the talks,” Kremlin spokesman Dmitry Peskov said, five weeks after Moscow began sending upwards of 150,000 of its own troops across Ukraine's border.

Meanwhile, Russia continued withdrawing some of its ground forces from areas around Kyiv after saying earlier this week it would reduce military activity near the Ukrainian capital and the northern city of Chernihiv to promote trust at the bargaining table.

While the Russians kept up their bombardment of those two zones, Ukrainian troops exploited the pullback on the ground by mounting counterattacks and retaking a number of towns and villages.

Still, Ukraine and its allies warned that the Kremlin is not de-escalating but resupplying and shifting its troops to the country's east for an intensified assault on the mostly Russian-speaking Donbas region in the country's east, which includes Mariupol.

The latest negotiations took place by video. At a round of talks earlier in the week, Ukraine said it would be willing to abandon a bid to join NATO and declare itself neutral — Moscow's chief demand — in return for security guarantees from several other countries.
