Ukraine carries out drone attack

Kyiv, Jan 31: Ukraine carried out another drone attack on an oil facility deep inside Russian territory, a military intelligence source in Kyiv told AFP on Wednesday.
Kyiv has ramped up strikes on Russian oil and gas facilities over the past two months, part of what it has called "fair" retaliation for Russian strikes on its own energy infrastructure.
The claim comes after the governor of Saint Petersburg said there had been a loud blast at an industrial site outside the northern city. Local media meanwhile reported that S-400 missiles systems had shot at a drone that crashed on an oil storage facility in the Nevsky district. AFP
