Two warehouses belonging to the Russian online retail giant Wildberries, were targeted overnight by new Ukrainian drone attacks, the company and local authorities said Thursday

One person was injured and more than 200 employees were evacuated after a drone attack sparked a fire in a Wildberries warehouse in the western Penza region, according to the regional governor, Oleg Melnichenko.

"Logistics chains have been reorganised; the receipt of goods and the dispatch of orders are being carried out at other sites," Wildberries said in a statement.

Another Wildberries warehouse was hit by a Ukrainian drone in Sarapul, about 1,100 km (685 miles) east of Moscow, and a fire broke out, according to the company.

Staff were evacuated and "according to preliminary information, no one was injured," Wildberries said in a separate statement.

Ukraine first targeted Wildberries warehouses on July 18–19 in the Tambov region about 480 km southeast of the Russian capital, as well as in the Moscow region, resulting in eight casualties and destroying facilities.

Since then, Ukraine has launched attacks on a number of the company's warehouses around the country.

More than four years after the launch of Russia's large-scale offensive against Ukraine, diplomacy is at a standstill and both countries are ramping up their long-range strikes.
