Russian attacks on Ukraine have killed at least nine people overnight, while Ukraine continues long-range drone strikes into Russia.
In Zaporizhzhia, Russian strikes killed six people, with three killed in Dnipropetrovsk.
There were also explosions in Ukraine's capital, Kyiv, with one wounded.
In Russia, a drone attack caused fires at a Wildberries site Voronezh.

Fires reported at energy plants deep into Russia, but cause unknown
As well as the reported attack on the Wildberries site, there have also been reports of fires at energy plants deep into Russian territory.
Unverified images on Telegram show smoke at a thermal power plant in Angarsk in the Irkutsk region, and separate posts show smoke at an oil refinery in Orsk.
There were also unconfirmed reports of a fire at a refinery at Komosomolsk-on-Amur, Khabarovsk, in the far east of Russia.
Our teams are working to verify the images and we are yet to see official statements.
Ukraine has carried out attacks deep into Russian territory in recent days.
On Monday, President Zelensky said a refinery in Tobolsk, Siberia was hit. "The distance was significant – more than 2,500 kilometres," he said.
Meanwhile, local officials said on Monday at least 13 people were killed in a Ukrainian drone strike more than 1,000 kilometres into Russia.
The strike overnight from Sunday into Monday in the region of Tatarstan injured more than 75.
One killed and two injured in Russia's Voronezh, with fires at Wildberries site
A drone attack in Russia’s Voronezh region has killed one and injured two overnight, according to regional governor Alexander Gusev.
One of those injured was at "a large logistics centre", Gusev writes on Telegram.
He adds that fires broke out at "two warehouses belonging to a major company".
Wildberries - known as "Russia's Amazon" - said this morning that its facilities had been attacked.
"The fire that broke out as a result of an attack on the company's logistics facilities in the Voronezh region has been extinguished. Fire crews continue to work at the site," the retailer said on Telegram.
Facilities were evacuated in advance, it adds, and "goods were mostly unaffected".
The company has been repeatedly targeted by Ukraine in recent weeks.
