At least five people were killed and 10 more injured in a Ukrainian drone strike on a warehouse close to Moscow overnight on Monday, the region’s governor has said.

The official did not specify what had been targeted but Ukraine has been carrying out strikes on facilities operated by Wildberries in recent weeks, often dubbed the “Russian Amazon”.

Kyiv says the depots are used to supply the Russian military, which Moscow denies.

Local officials also said Wildberries warehouses were targeted in the St Petersburg and Tver regions overnight.

Russia also launched strikes against parts of Ukraine, killing at least four and injuring several people.

Russia’s defence ministry said it had intercepted and destroyed 320 drones overnight.

Moscow region governor Andrei Vorobyov said an industrial site in Novoselki, Chekhov – about 69km (43 miles) south of the Kremlin – was attacked.

A warehouse was hit and caught fire, he said, while an electrical substation and an administration building were also damaged.

He wrote on Telegram that seven of the 10 people injured were in a moderate condition, with one in a serious condition.

Ukrainian media reported that the warehouse site was linked to Wildberries. It was listed on Russia’s Yandex search engine as being a Wildberries location.

The company has not commented publicly but confirmed its facility in St Petersburg was hit.

Meanwhile, Ukraine’s State Emergency Service said an 89-year-old woman was killed and two girls, aged two and 12, were among seven injured in a Russian strike on the southern port city of Mykolaiv overnight.

A woman and two girls, aged five and 10, were killed in a strike on a residential area in Sumy, and another four people were injured, it said.

Russian strikes also injured two people in the city of Bilhorod-Dnistrovskyi, while a food warehouse was set on fire in Dnipro, according to the State Emergency Service.

It comes a day after a busy beach in southern Russia was hit by a drone, killing seven people and injuring 58, according to Russian officials.

Social media footage verified by the BBC shows a drone crashing an exploding on a beach in the Krasnodar region as tourists look on from the shore and in the water.

Some Ukrainian Telegram channels have claimed it crashed onto the beach as a result of electronic warfare which jammed the drone’s signal, while eyewitnesses were quoted by Russian media as saying gunfire preceded the explosion, indicating that air defences may have tried to shoot the drone down.

The area’s regional governor accused Ukraine of “a deliberate strike on civilians”. Ukraine has not commented.

Both sides deny targeting civilians deliberately.
