Earlier, it was reported Ukraine's claims that a Russian missile crossed into Moldovan and Romanian airspace - although Romania says it did not detect a missile in its territory.
Now, we have reaction from Moldova's President, who says a Russian missile was detected crossing Moldova.
Maia Sandu says on X: "While our countries celebrate Christmas, Kremlin chooses destruction - targeting Ukraine's energy infrastructure and violating Moldova's airspace with a missile, actions that clearly violate international law.
"Moldova condemns these acts and stands in full solidarity with Ukraine."
As we've been reporting, Kharkiv, Ukraine's second-largest city, has been one of the areas under Russian attack.
In the past hour - while most of Ukraine has quietened down - Kharkiv still had air raid warnings in place.
At 13:06 local time (11:06 GMT), the Ukrainian air force announced the presence of enemy drones near the city and urged people to stay in shelters. It later made a similar warning.
Kharkiv's mayor, Ihor Terekhov, says, as of 13:48 local time, damage to 74 buildings had been recorded from today's attacks. Terekhov also says repairs to the energy infrastructure are in progress, and 35% of the circuits have been fixed.
Four people have been killed and five more injured by Ukrainian shelling in the town of Lgov in Russia's Kursk region, according to the region's acting governor.
Alexander Khinshtein says a five-storey building, two single-storey residential buildings, and a single-storey beauty salon were damaged.
He adds that the "blast wave" destroyed a small section of a gas pipeline, blew out windows in neighbouring homes, and damaged at least a dozen cars.
Parts of the Kursk region are occupied by Ukraine following its surprise cross-border offensive in early August.
Last week, Khinshtein said five people had been killed in the region, after a Ukrainian strike.
Meanwhile, in Vladikavkaz in Russia's North Ossetia region, a woman was killed after debris from an intercepted Ukrainian drone fell on a shopping centre, according to Russia's defence ministry.
