Ukraine's air force said on Friday Russia attacked it with 72 drones overnight though it downed 33 of them while 34 others disappeared from radar without reaching their targets.

Here are the key developments on the 1,052nd day of Russia’s full-scale invasion of Ukraine. Here is the situation on Saturday, January 11:

Ukraine's long-range drone strikes on airbases and ammunition depots inside Russia have reduced the glide-bomb threat.

Ukraine has launched a new offensive in Russia’s region of Kursk. But it’s not clear why exactly Ukraine is waging a new assault in Kursk, and why now.

At the event, Ukraine presented various drones, including the Shrike and Vampire, that are used in combat against Russia. On October 19, 2023, Shrike drones attacked a Russian convoy. A total of 35 drones were deployed, destroying eight tanks and four infantry fighting vehicles valued at $19 million.

Ukrainian President Volodymyr Zelenskyy said that some 38,000 Russian troops have been killed or wounded fighting in Russia's western Kursk region since August.

Ukraine has launched a counterattack in the southern Russian border region of Kursk, warning that Russia is “getting what it deserves.”

Ukraine has largely been driven out of Kurakhove, a battered but strategic town in the Donbas, Russia said. Kyiv’s forces were pressing a renewed offensive in southern Russia.

The claim, which drew no response from Ukrainian authorities, came a day after the Russian Defense Ministry said Ukrainian forces had pressed new attacks in Russia’s Kursk border region.
