Overnight, Moscow's missile and drone strikes have caused blackouts in extensive areas of Ukraine's capital, Kyiv.

Moscow has intensified strikes on power infrastructure over the last fortnight, while the country's government has requested "substantial measures" from allies to increase pressure on Russia.

A series of attacks damaged energy infrastructure and apartment buildings in Kyiv.
Several of the people injured in the assaults on the capital have been transported for medical care, as confirmed by municipal representatives.
Regional authorities said the metropolitan region experienced intense attacks overnight. A seven-year-old child lost their life and three other people were wounded.
