Russia launched 188 drones against most regions of Ukraine in a night-time blitz, the Ukrainian air force said on Tuesday, describing it as a record number of drones deployed in a single attack.

Most of the drones were intercepted, according to the air force, but apartment buildings and critical infrastructure such as the national power grid were damaged.

No casualties were immediately reported in the 17 targeted regions.

The Russian Defence Ministry, meanwhile, issued a rare official acknowledgement of its assets recently being hit on its own soil by US-made ATACMS missiles, after President Joe Biden authorised Ukraine to use the longer-range weapons to strike deeper inside Russia.

Russia has been hammering civilian areas of Ukraine with increasingly heavy drone, missile and glide bomb attacks since the middle of the year.

At the same time, Russia’s army has largely held the battlefield initiative for the past year and has been pushing hard in the eastern Donetsk region where it is making significant tactical advances, according to Western military analysts.

Ukraine faces a difficult winter, with worries about the reliability of the electricity supply amid Russia’s attacks and how much US support it can count on next year after President-elect Donald Trump takes office in January.

The Russian Defence Ministry said five US-made Army Tactical Missile System (ATACMS) missiles were fired at one of its air defence missile systems in Russia’s Kursk border region on Saturday.

It said three of the missiles were downed by the Pantsyr short-range air defence systems protecting the position but that two other missiles hit it, injuring an unspecified number of servicemen and damaging the system’s radar.

In another attack with ATACMS on Monday, eight of the missiles were launched at the Kursk-Vostochny military air base near Khalino. Seven of them were shot down and one hit the facility, injuring two servicemen and causing minor damage, the ministry said.

“Preparations for retaliatory action are under way,” the ministry said without elaborating.

A US official said on November 19 that ATACMS had been fired at targets inside Russia for the first time.

As Russian Shahed drones spread out across Ukraine late Monday, the air raid alert in the Kyiv region overnight lasted more than seven hours. Russia is trying to unnerve civilians and wear down their will to resist in the war, military analysts say.

Ukraine President Volodymyr Zelensky noted that each Shahed has 85 foreign components and that Russia obtained them by circumventing international sanctions. He said on the Telegram messaging app that “we need more joint effort so that the sanctions work and force Russia to stop this war”.

Meanwhile, Ukraine’s General Staff said on Tuesday that, over the past 24 hours, roughly half of the clashes along the about 600-mile (1,000km) front line occurred near Pokrovsk and Kurakhove in the Donetsk region.

Ukraine has a critical manpower problem on the front line and, though the Russian army’s gains have been incremental, its momentum is adding up as the Ukrainians yield ground.

The Russian advance is threatening important supply routes in Donetsk, the Washington-based Institute for the Study of War said late on Monday.

Ukrainian defences in Donetsk are not in danger of being overrun, however, the think tank said.

It also noted that Russia would need to capture more than 3,000 square mile (8,000 sq km) of territory to achieve the Kremlin’s goal of seizing the whole of Donetsk.

In other developments, a court in Russia’s Kursk region has ordered a British national fighting with Ukraine to be held in detention pending an investigation and trial.

The ruling on the Briton, identified by state news agency Tass and other media as James Scott Rhys Anderson, was announced on Tuesday by court officials, who said in an online statement that it was handed down the previous day.

The hearing took place behind closed doors in Leninsky District Court in the city of Kursk.

It was not clear from the statement what charges Mr Anderson is facing and whether he is considered a prisoner of war by the Russian authorities.

He was reportedly captured in the Kursk region, where Ukrainian forces have seized territory following a lightning offensive in August.
