Russian strikes in recent days have wiped out more than half of Ukraine¡¯s domestic natural gas production, likely forcing the war-battered country to spend €1.9 billion ($2.2 billion) on fuel imports to survive the looming winter.

Kyiv told its allies earlier this week that a massive Russian barrage targeting the Kharkiv and Poltava regions on Oct. 3 took out roughly 60% of the country¡¯s gas production, according to people with knowledge of the matter. They requested anonymity because the discussions are private.

Ukraine¡¯s gas infrastructure ¡ª able to meet domestic demand before the Russian full-scale invasion ¡ª has come under increasingly intensive missile and drone strikes since the beginning of this year.
