A Russian guided aerial bomb attack on the northeastern Ukrainian city of Kharkiv overnight injured six people and sparked several fires, regional officials said on Wednesday.
Five of those injured, all adults, have been hospitalized, Oleh Synehubov, governor of the broader Kharkiv region, said on the Telegram messaging app.
Ihor Terekhov, mayor of Kharkiv, Ukraine's second-largest city that is also the capital of the Kharkiv region, said the attack also sparked a fire at one of the city's markets and at some residential buildings.
Photos and videos showed firefighters battling through the night as flames engulfed what appeared to be market stalls and other structures.
The Kharkiv region, which lies near the border with Russia, has been the target of regular Russian aerial attacks since the start of the war.
There was no immediate comment from Moscow about the attack.
EU discusses drone wall after Russian incursions
This comes as the European Union discussed proposals for a "drone wall" to protect the continent at a summit on Wednesday in Copenhagen, just days after airspace intrusions by unidentified unmanned aircraft forced a temporary closure of Danish airports.
France, Germany, Sweden, Norway, the Netherlands, Britain, Finland, and Ukraine have committed troops and anti-drone systems to help Denmark protect the leaders, many of whom have accused Russia of brazen violations of European airspace with recent incursions by drones over Poland and fighter jets over Estonia.
Denmark has stopped short of saying who it believes is responsible for the incidents in its airspace last week, which disrupted air traffic at six airports, but Prime Minister Mette Frederiksen has suggested it could be Moscow.
Russia has denied responsibility for the drones over Denmark, disputed that its fighter jets entered Estonian airspace, and said it did not intend to send drones into Poland.
But the incidents prompted European leaders to step up calls to bolster the continent’s defenses and boost support for Ukraine in its fight against Russia’s invasion. US President Donald Trump has demanded the EU take more responsibility on both fronts.
European Commission President Ursula von der Leyen floated the idea last month, just hours after some 20 Russian drones entered Polish airspace, although officials say it had been in the works before then.
The Commission, the EU’s executive body, has not yet produced a detailed plan, leaving open questions about the cost and practicalities. But NATO Secretary General Mark Rutte praised the idea on Tuesday as “timely and necessary”.
