July 24 (UPI) -- Russian online retail giant Wildberries came under attack overnight by Ukrainian forces for the fifth time in six days after drone strikes on logistics facilities of the firm in and around St. Petersburg.

Wildberries warehouses at Utkina Zavod logistics park in Vsevolozhsk District, just beyond the St. Petersburg city limits, and Shushary, 9 miles south of downtown, were set ablaze after being hit, together with other "civilian infrastructure" along the main highway linking the city with Moscow.

Major fires were reported at both Wildberries facilities.

Leningrad provincial head, Gov. Alexander Drozdenko, said three people were hospitalized after being injured but provided no further details.
