Moscow buildings hit by drones
Russia has accused Ukraine of launching a series of early morning drone attacks on Moscow, BBC News reports.
The Russian defence ministry said on Telegram that Kyiv had staged a "terrorist attack" using at least eight drones.
Officials said that minor damage had been caused to several buildings.
The capital city's mayor, Sergei Sobyanin, says no-one was seriously injured. Emergency services were "at the scene of incidents", he said.
The defence ministry claimed that all the drones were intercepted.
"Three of them were suppressed by electronic warfare, lost control and deviated from their intended targets. Another five drones were shot down by the Pantsir-S surface-to-air missile system in the Moscow region," the ministry said.
Earlier, media reports had said as many as 30 drones were involved. Authorities have also said several of them fell on buildings after being downed.
There has been no comment from Kyiv, but on Monday, the head of Ukraine's military intelligence, Gen Kyrylo Budanov, warned of a swift response to a series of Russian missile strikes on Kyiv.
Images posted on social media showed traces of smoke in the sky above the Russian capital. Others showed a broken window.
The strikes on Moscow follow an overnight drone attack on the Ukrainian capital, Kyiv, in which at least one person was reported killed.
