Ukraine has shot down 14 attack drones and a cruise missile fired by Russia at its south and east, with debris damaging a warehouse at the Black Sea port of Odesa, officials say.
Air defences brought down nine Iranian-made Shahed drones over the southern region of Odesa overnight, which is home to Ukraine's main Black Sea ports, and no one was reported injured, governor Oleh Kiper wrote on the Telegram messaging app.
There was no comment from Moscow, which denies targeting civilian infrastructure.
Russia has intensified attacks on port and grain infrastructure since quitting a UN-brokered deal in July that had allowed Kyiv to ship its grain via the Black Sea.
Ukraine, a major grain producer, has been trying to establish a new shipping corridor to revive its exports across the Black Sea, traditionally its main route to global markets, despite a de facto Russian blockade.
The regions of Kherson in the south, Donetsk in the east and Sumy in the northeast were also targeted in the attack, the Interior Ministry said.
All 14 drones, including 13 Shaheds, and a cruise missile were shot down in the strike, the air force said on Monday, praising air defence systems supplied by the West.
"Western weapons have proven and continue to prove their effectiveness on the battlefield," Mykola Oleshchuk, commander of the air force, wrote in a statement on Telegram.
Russia has carried out frequent air strikes across Ukrainian regions since launching its full-scale invasion in February 2022. Kyiv fears Russia is going to step up attacks on its power grid to cripple infrastructure as winter begins to set in.
President Volodymyr Zelenskiy's office said Russian shelling hit a thermal power station in Donetsk region on Sunday evening. The Interior Ministry said there had been a large fire.
DTEK, Ukraine's largest private energy company, reported one of its thermal power stations had been shelled by Russia but provided no further details.
