Russia has reported that Ukraine conducted a drone attack on Moscow overnight for the second consecutive night.
To ensure safety, all four major airports in the capital were temporarily closed but have since reopened, according to Rosaviatsia, Russia's aviation authority, on Telegram.
Moscow's mayor, Sergei Sobyanin, announced on social media that at least 19 Ukrainian drones were intercepted before reaching the city from various directions. He noted that some debris fell onto a major highway leading into the city, but fortunately, there were no reported injuries.
Ukraine has yet to respond to these claims. Meanwhile, the mayor of Kharkiv indicated that Russian drone strikes also targeted the city and the Kyiv region overnight.
In addition to Moscow, officials from other Russian cities, including Penza and Voronezh, reported drone activity during the night leading into Tuesday.
Unverified accounts from Russian military bloggers mentioned that windows in an apartment building in southern Moscow were damaged.
This marks the second consecutive night that Russia has reported a Ukrainian drone attack; on Monday, the Russian defense ministry claimed to have destroyed 26 Ukrainian drones overnight.
Since the onset of Russia's full-scale invasion of Ukraine over three years ago, Kyiv has executed multiple drone strikes on Moscow, with the most significant attack in March resulting in three fatalities.
This follows reports on Monday of renewed Ukrainian efforts to penetrate Russia's Kursk region.
Kyiv stated that it targeted a drone command unit in the Kursk area on Sunday, near the Russian village of Tyotkino, according to the Ukrainian military.
In April, Moscow declared it had regained control of the entire region, nine months after Ukrainian forces launched a surprise invasion. However, Kyiv maintains that it still has troops operating within Russian territory.
Additionally, in Kursk, Russian officials reported that an electrical substation in Rylsk lost power on Monday due to damage from a Ukrainian attack.
According to Alexander Khinshtein, the acting governor of the Kursk region, two transformers at the Rylsk substation were damaged, and two teenagers sustained injuries from shrapnel.
Various Russian military bloggers also reported that Ukrainian forces attempted to breach the border near Tyotkino, sharing images—yet to be verified by the BBC—of vehicles navigating through tank traps.
On Monday, Ukrainian forces reportedly launched missiles across the border and traversed minefields using specialized vehicles, as per the bloggers.
"The enemy detonated bridges with rockets overnight and initiated an assault with armored units in the morning," blogger RVvoenkor stated, according to Reuters.
"The mine-clearing vehicles began creating paths through the minefields, followed by armored vehicles carrying troops. Intense fighting is occurring at the border."
In a statement on Monday, Ukraine asserted: "Nine months after the commencement of the Kursk operation, Ukraine's Defense Forces continue to maintain a military presence in Russia's Kursk region."
While Moscow has not issued an official response, some military bloggers have circulated maps indicating opposing forces attempting to cross the border in two locations towards Tyotkino, close to where the drone command unit was struck.
Meanwhile, in Sumy—approximately 12 kilometers from Tyotkino in northeastern Ukraine—local authorities have advised residents to evacuate from two settlements, as reported by Reuters.
Ukraine's initial surprise incursion into Kursk occurred in August 2024, aimed at establishing a buffer zone to safeguard Sumy and surrounding areas, while also hoping to leverage it in future negotiations.
