Ukraine said it destroyed two "Valdai" radar systems near Moscow in a wave of overnight drone attacks, while Moldova said two Russian drones exploded on its territory and NATO member Romania said its airspace had likely been breached.
Ukraine's Main Intelligence Directorate (GRU) said in a statement on February 13 that the strikes targeted a military unit in the Russian city of Dolgoprudny that is responsible for the security of the airspace over Moscow.
"The explosive device destroyed two Russian Valdai radar systems designed for 24-hour automatic detection and counteraction of UAVs. This is the latest development of the Russian military-industrial complex -- the first model in its class adopted by the army of the aggressor state of Russia," the GRU statement said.
Russia has not commented on the GRU claims.
Moscow launched a massive attack of its own in the early hours of February 13, targeting Ukraine's southern Odesa region.
Oleh Kiper, head of the district's military administration, said the attack damaged port infrastructure and an inactive educational institution.
As local residents captured videos of the attack, multiple flying objects were observed in the night sky over the region. Ukrainian authorities had declared an air raid alert in the city of Izmayil, in the southwestern part of Ukraine, near its borders with Romania and Moldova.
Moldovan President Maia Sandu said two Russian Shahed drones violated Moldova's airspace and exploded on its territory, while Romania's Defense Ministry said the two drones likely breached its airspace.
"Russia does not respect borders, attacks civilians, and spreads terror. Its war against Ukraine is criminal. Leave us, peaceful nations, alone," Sandu wrote on social media platform X.
Mihai Popsoi, Moldova's foreign minister, said the Russian ambassador would be summoned over the incidents.
The latest drone strikes highlight the escalating aerial conflict between Ukraine and Russia, with both sides launching cross-border attacks. Ukraine has increasingly targeted Russian territory with drones, while Russia continues to bombard Ukrainian infrastructure, often striking civilian areas.
In the Ukrainian city of Kherson, Russian shelling damaged a multi-story residential building, injuring two people, according to Oleksandr Prokudin, the governor of the Kherson region.
Across the border in Russia, the Lipetsk region was struck by Ukrainian drones, leading to temporary power outages in its administrative center also called Lipetsk.
Lipetsk Governor Igor Artamonov reported the drone threat on Telegram and later confirmed that electricity had been restored in several affected areas.
Artamonov stated that debris from one of the drones fell on an aeration station, injuring an employee. Additional drone wreckage was found at two private residences, though no casualties were reported.
