At least six people were injured in an overnight Russian drone attack on Ukraine's Kharkiv and Dnipropetrovsk regions, according to local officials, while a Russian official said that at least five people were injured in an explosion in the city of Belgorod, near the Ukrainian border.
The Ukrainian Air Force said on May 4 that 13 drones launched by Russia had been shot down, but regional officials said that debris caused injuries and hit critical infrastructure and commercial and residential buildings.

Kharkiv regional Governor Oleh Synyehubov, writing on Telegram, said a 13-year-old child and a woman had been hospitalized due to injuries sustained in the strikes.
Emergency services were bringing a fire at an office building hit by debris under control, Synyehubov added.
Two people were reported injured in the Dnipropetrovsk region, according to Governor Serhiy Lysak. He said infrastructure and three houses were damaged.
Russia has recently intensified its attacks on the Kharkiv region, whose capital lies just 30 kilometers from the Russian border. Ukrainian troops recaptured substantial amounts of territory in the region in the fall of 2022.
Kharkiv has been targeted by Russian drones and missiles nearly every day for months, raising fears that Moscow could be planning a renewed campaign to capture it.
Major General Vadym Skibitskiy said on May 3 that Russia, which launched the full-scale invasion against Ukraine in February 2022, is trying to exploit its current advantage in weapons and manpower.
"Our problem is very simple: We have no weapons," Skibitskiy was quoted as saying in an interview with The Economist.
In Russia, regional Governor Vyacheslav Gladkov wrote on Telegram that at least five people were injured and some 30 residences damaged following an explosion in Belgorod, a city about 40 kilometers from the Ukrainian border.
Some local Telegram channels suggested the explosion could have been caused by an errant Russian missile.
Kyiv did not comment on the report.
Belgorod has been hit repeatedly over the months by Ukrainian strikes. While casualties have been relatively low, the attacks have rattled local residents and caused many people to leave the city, which had a prewar population of about 333,000.
Separately, the Russian Defense Ministry said its forces shot down four U.S.-made long-range missiles fired by Ukraine over the Russian-occupied Crimea Peninsula.
The claim could not be verified, but Washington has reportedly begun shipping Army Tactical Missile Systems (ATACMS) to Kyiv in recent weeks.
Ukrainian President Volodymyr Zelenskiy has continued to press for the speedy delivery of promised Western military aid, singling out the need for armored vehicles, ammunition, and missiles.
