One person was killed and more than a dozen others wounded in Russia’s latest aerial attack on Ukraine, which targeted the southern port city of Odesa, officials said on Friday.

Emergency services published images of firefighters helping a woman in pyjamas climb from the window of a housing block in flames.

Both Moscow and Kyiv have stepped up their drone and missile attacks after three years of war and peace talks initiated by the United States appear closer to collapse.

“Russia continues its tactics of deliberate terror against our people,” Ukrainian leader Volodymyr Zelensky said in response on social media.

“And it is precisely for this that it must face a strong response — one that will significantly impact Russia as a whole and its ability to continue the war,” he added.

Ukrainian officials said one person was killed and at least 13 were wounded in Odesa, including three rescue workers who were hurt at the scene of the attack.

The governor said homes, educational facilities and civilian infrastructure were damaged in the attack.

The air force said Russia had launched 86 drones in the barrage and that 70 had been downed by air defence systems.

The Russian defence ministry, meanwhile, said its forces had eliminated at least 61 Ukrainian drones. It also said its forces had gained ground in the Kharkiv region.

Four people in Kharkiv city and its suburbs were wounded in separate Russian drone attacks, including two girls aged 12 and 17, emergency services said.

Odesa, one of Ukraine’s largest port cities and a UNESCO heritage site, has been under persistent Russian attacks since Moscow invaded its neighbour early in 2022.
