KYIV: Kyiv’s metro system temporarily closed on Saturday due to power shortages, the operator said, amid recent Russian attacks on Ukrainian energy infrastructure. The Kyiv metro is a vital transport artery for the capital and rarely pauses operations, even during intense Russian bombardment. Around 800,000 passengers use the system daily, according to data published last year. Many of them rely on it to commute to work. Residents also use its 52 stations as bomb shelters during Russian attacks.
