Five people have been killed and 61 injured after Russia launched a mass drone and missile strike overnight, Ukrainian officials have said.

In the region that suffered the worst casualties, two children were among the 51 wounded in Kharkiv late on Friday, the regional prosecutor’s office said, while one person was killed, according to the regional state administration head.

Then four people were killed and eight others were injured in Donetsk Oblast, the regional governor said on Saturday.

And two more people were also injured in Sumy Oblast, according to the regional military administration.

Russia attacked Ukraine overnight with 183 drones and two ballistic missiles, the Ukrainian air force said early on Saturday, with 77 shot down and another 73 falling without causing any damage.

The attack comes as US officials finalised new economic sanctions against Russia to intensify pressure on Moscow to embrace president Donald Trump’s efforts to end its war, sources say.

The targets include state-owned energy giant Gazprom and major organisations in the natural resources and banking sectors, an administration official said. Mr Trump would need to approve the package.
