Ukraine has reported that Russia has attacked its energy infrastructure 60 times in recent weeks, raising concerns that Russia may be launching a campaign of attacks on the power grid for a second winter. Last winter, Russia targeted Ukraine's power sector, causing widespread blackouts. Ukraine's military spy agency believes Russia has stockpiled missiles for a winter air campaign. While Ukraine has improved its air defenses, its energy system remains vulnerable from last year's attacks. The government is urging its partners for support and assistance in protecting its energy sector.
