KYIV, Ukraine, April 9, 2025 (BSS/AFP) - At least 21 Ukrainians were wounded during Russian attacks across the country overnight, regional officials said on Wednesday, as Moscow stepped up its aerial bombardment despite US efforts to secure a ceasefire.

The worst attack left 15 people wounded in the central Ukrainian industrial region of Dnipropetrovsk, the governor Sergiy Lysak wrote on social media.

He posted images of several damaged buildings and said the victims were between 18 and 87 years old, adding that eight people were admitted to hospital.

The Ukrainian air force said that Moscow had launched 55 drones overnight and that its air defence units shot down 32 of the unmanned aerial attack aircraft.

In the eastern region of Donetsk, which the Kremlin claims is part of Russia, the governor said three people were wounded -- an 11-year-old girl, her mother and grandmother -- in a "massive" drone attack on the frontline city of Kramatorsk.

In the Zaporizhzhia region, another that the Kremlin says it annexed in late 2022, authorities said a 60-year-old man was wounded.

In the eastern Kharkiv region that borders Russia, a 65-year-old man and 50-year-old woman were wounded in an attack on civilian enterprises, local officials said.

US President Donald Trump's administration has held several rounds of talks with both Ukrainian and Russian officials hoping to secure a halt in fighting, without seeing any tangible results.

The Russian defence ministry, meanwhile, said it had shot down 158 Ukrainian drones over the west and south of the country, temporarily disrupting operations at several civilian airports.
