Air raid sirens have blared across the Ukrainian capital, Kyiv, as Russia kept pounding the city for a second night in a row. The drone attacks early on Monday targeted critical infrastructure in Kyiv and the surrounding region, according to Ukrainian officials, and have wounded at least one person. "It is loud in the region and in the capital: night drone attacks," said Oleksiy Kuleba, the governor of the Kyiv region. "Russians launched several waves of [Iranian-made] Shahed drones. Targeting critical infrastructure facilities," he wrote on the Telegram messaging application.
