A timeline of attacks on Russian territory during the Ukraine war.
Russia has suffered high-profile attacks since it invaded Ukraine in February. Some have taken place on Russian soil, while others have damaged or destroyed significant military assets. All have exposed security lapses embarrassing to the government in Moscow. In some cases, Ukraine has hinted that it is responsible.
In the latest cases, a drone hit an oil facility in the Russian province of Kursk on Tuesday, a day after Ukrainian drones struck two bases deep inside the country.
Here is a timeline looking at some other attacks.
Beginning in April: Strikes near Ukraine’s border
Two low-flying Ukrainian helicopters crossed into Russia and fired on an oil depot in the city of Belgorod, just 20 miles from the border. The attack on April 1, reported by a regional governor, was the first time since the full-scale invasion began that Russia had reported a Ukrainian airstrike on its territory.

Since then, there have been repeated strikes in the region, which served as a staging point for the invasion. In July, Russia blamed Ukraine for attacks in the center of Belgorod that killed four people, while there were more than a dozen explosions in mid-October.
Explosions also ripped through oil depots in late April in the Russian city of Bryansk, a key logistical hub less than 100 miles from the Ukrainian border and 200 miles from Belgorod.
Mid-April: Missile attack on Russia’s Black Sea flagship
In mid-April, two Ukrainian Neptune missiles hit Russia’s flagship, the Moskva, in the Black Sea, about 65 nautical miles south of Odesa, Ukraine. The ship later sank, and many sailors died. The Russian government said only that the ship sank following an accidental fire caused by an explosion.
Afterward, some Russian commentators asked why the pride of the country’s Black Sea fleet had not been better protected.
August: Explosions at a Crimea air base
Explosions struck the Saki Air Base in Crimea, a region illegally annexed by Moscow in 2014, in early August. Russian authorities said munitions stored at the site had blown up, but satellite images appeared to show at least eight wrecked warplanes. A senior Ukrainian official said the blasts were an attack carried out with the help of partisans.
August: A car bomb near Moscow
Daria Dugina, the daughter of a prominent Russian nationalist, was killed when her vehicle exploded in a Moscow suburb in August. U.S. officials said later they believed that Ukraine’s government authorized the attack, and some American officials said they suspected that Ms. Dugina’s father, Aleksandr Dugin, a Russian ultranationalist, was the actual target.
Early October: The Crimea bridge explosion
Early on Oct. 8, an explosion destroyed part of a road and rail bridge that connects Russia with the Crimean Peninsula. The attack was a blow to Moscow’s war effort, since the bridge served as the main supply route for its forces in southern Ukraine.
In addition, President Vladimir V. Putin of Russia had claimed personal credit for the bridge project. When it opened in 2018, he drove a truck along its 12-mile length. The government in Kyiv did not officially claim credit for the attack, but it was celebrated by many Ukrainians.
October: A sea drone attack in Crimea
Russia accused Ukraine of launching a drone attack on its Black Sea Fleet in Crimea in late October and said that one minesweeper sustained minor damage. A senior Ukrainian official said the vessel had been severely damaged and footage, never confirmed, later emerged of a sea drone heading toward a ship as gunfire peppers the water around it.
