Kyiv: In Moscow's sixth aerial assault on Kyiv in as many days, Ukrainian air defences downed more than 30 Russian cruise missiles and drones, according to local authorities on Friday. According to senior Kyiv official Serhii Popko on Telegram, Iranian-made Shahed drones and cruise missiles fired from the Caspian Sea simultaneously attacked the Ukrainian capital from various directions. According to Ukraine's Prosecutor General's Office, the attack left a 68-year-old man and an 11-year-old child injured, and falling debris also caused damage to homes, outbuildings, and cars.

On 17 days last month, including daytime attacks, Kyiv was the target of drone and missile attacks. However, a Washington-based think tank called the Institute for the Study of War warns that Moscow's plan could go awry.

According to Valerii Zaluzhnyi, the chief of staff of Ukraine, all 15 cruise missiles and 21 attack drones were shot down by Ukrainian air defences. Meanwhile, Ukraine once more launched attacks on Russian border regions. These regions of Russia have also been alarmed by recent cross-border raids, which has the Kremlin on high alert. That might be a Ukrainian tactic to scatter Russian forces ahead of the start of a counteroffensive. The decision of whether to (strengthen) defences in Russia's border regions or reinforce their lines in occupied Ukraine presents Russian commanders with a serious dilemma, the UK ministry of defence said on Friday. According to regional governor Roman Starovoit on Telegram, air defence systems in Russia's southern Kursk region, which borders Ukraine, shot down "several Ukrainian drones" overnight on Thursday. Ukrainian forces shelled two villages on Friday morning, according to regional governor Alexander Bogomaz of the neighbouring Bryansk region, which also borders Ukraine. There were no casualties reported. In the early hours of Friday, two drones reportedly also attacked energy facilities in western Russia's Smolensk region, which borders Belarus.

The incursions, according to Ukraine, are carried out by Russian volunteer fighters, not its military
