A drone strike on an industrial zone outside the Russian capital killed five people and wounded six others, the region's governor said as Moscow and Kyiv traded attacks.

Ukraine has conducted long-range strikes targeting civilian infrastructure in Russia, and in recent weeks stepped up attacks on warehouses belonging to the Russian e-commerce giant Wildberries.

Ukraine often fires hundreds of drones into Russia each night, in retaliation for Russia launching hundreds of its own drones and dozens of missiles at Ukrainian towns and cities.

Moscow's regional governor Andrey Vorobyov said early Tuesday that several fires broke out following a drone strike in the Novoselki industrial zone outside the Russian capital.

'According to preliminary information, five people were killed and a further six wounded,' he said on Telegram.

Drones also damaged a warehouse near Krasny Bor in northwestern Russia, wounding one person, according to Leningrad regional governor Aleksandr Drozdenko.  

In Ukraine, Russian attacks killed two children and an elderly woman in Sumy in the country's north-east overnight. 

'Two children and an elderly woman were killed in Russian [guided aerial bomb] strikes on Sumy tonight,' Oleg Grygorov, the head of the regional military administration, said this morning. 

'The girls were 5 and 10 years old. The children's bodies were recovered from under the rubble of their house.' 

Six guided aerial bombs struck civilian infrastructure in the city, including residential and non-residential buildings, Mr Grygorov said.

Another attack on the port city of Mykolaiv in southern Ukraine killed an 89-year-old woman.  

Russia launched its full-scale offensive against Ukraine in February 2022, and has regularly struck its neighbour, including from the Crimean peninsula.

Ukraine's front lines were little changed in July as its forces largely stalled Russia's momentum, according to AFP analysis of data from the Institute for the Study of War.

Russia said this morning that its forces hit four cargo vessels used by Ukraine's military and a vehicle parts plant at the Ukrainian port of Chornomorsk.

Russia's Defence Ministry said that two dry cargo ships had been hit in the Ukrainian ports of Mykolaiv and Pivdennyi on Monday evening and that two more vessels carrying weapons and military equipment to Ukrainian ports had been struck south of Odesa.

'As a result of the strikes... the following targets were hit: in the port of Chornomorsk - the Chornomorsk Automotive Components Plant and a port terminal where the Ukrainian Armed Forces were repairing military vehicles and storing ammunition and fuel,' the ministry said. 

Reuters could not independently verify Russia's assertions. 

Ukraine also attacked a Russian cargo ship overnight off the coast of Novorossiysk in the Black Sea. 

Footage from the attack showed several shipping containers on fire as the ship, named 'Nadezhda', stood still. Local media reported that Ukraine sent up to seven drones. 

Smoke could be seen billowing out of its bow. Additional footage, taken from the deck of the ship, showed bloodied members of crew recovering from the attack. 

It also showed damage across the full length of the ship, though the attack appears to have been concentrated at the front. 

On Sunday night, Russia was forced to shoot down nearly 1,200 drones sent by Ukraine. 

One of these drones struck a beach near Vladimir Putin's £1billion palace bolthole.

Russia claimed that 7 people were killed in the alleged attack on the town of Arkhipo-Osipovka, near the Black Sea resort of Gelendzhik. 

Among those allegedly killed were three children. A further 40 people were injured, with 17 needing to go to hospital.
