The Ukrainian village of Ocheretyne has been battered by fighting, drone footage obtained by the Associated Press shows. The village has been a target for Russian forces in the Donetsk region of eastern Ukraine.

Russian troops have been advancing in the area, pounding Kyiv’s depleted, ammunition-deprived forces with artillery, drones and bombs. Ukraine’s military has acknowledged the Russians have gained a “foothold” in Ocheretyne, which had a population of about 3,000 before the war, but says that fighting continues.

Residents have scrambled to flee the village, among them a 98-year-old woman who walked almost 6 miles alone last week, wearing a pair of slippers and supported by a cane, until she reached Ukrainian front lines.

Not a single person is seen in the footage obtained late Friday, and no building in Ocheretyne appears to have been left untouched by the fighting. Most houses, apartment blocks and other buildings look damaged beyond repair, and many houses have been pummeled into piles of wood and bricks. A factory on the outskirts has also been badly damaged.

The footage also shows smoke billowing from several houses, and fires burning in at least two buildings.

Elsewhere, Russia has in recent weeks stepped up attacks on Kharkiv, Ukraine’s second-largest city, in an attempt to pummel the region’s energy infrastructure and terrorize its 1.3 million residents.

Four people were wounded and a two-story civilian building was damaged and set ablaze overnight after Russian forces struck Kharkiv, in northeastern Ukraine, with exploding drones, regional Gov. Oleh Syniehubov said Saturday. The four, including a 13-year-old, were hurt by falling debris, he said on the Telegram app.

Russian state agency RIA reported Saturday that Moscow’s forces struck a drone warehouse in Kharkiv that had been used by Ukrainian troops overnight, citing Sergei Lebedev, described as a coordinator of local pro-Moscow guerrillas. His comments could not be independently verified.

Russian forces continued hitting Kharkiv and its surroundings on Saturday, according to updates posted by Syniehubov and other Ukrainian officials on the Telegram messenger app. One strike hit a civilian business in an industrial district of the city, wounding at least six people, Syniehubov said. Another attack killed a civilian outside his house in Slobozhanske, a village northeast of the city, the governor reported.

In the Black Sea port of Odesa, which has been repeatedly targeted in recent days, three people were hurt in a rocket attack on “civil infrastructure,” regional Gov. Oleh Kiper said.

Ukraine’s military said Russia launched a total of 13 Shahed drones at the Kharkiv and Dnipropetrovsk regions of eastern Ukraine overnight, all of which were shot down by Ukrainian air defenses.

Ukraine’s energy ministry on Saturday said the overnight strikes damaged an electrical substation in the Dnipropetrovsk region, briefly depriving households and businesses of power.
