One dead in strike on Odesa maternity ward, officials say

Russia has launched a "massive" drone attack on the capital, Kyiv Mayor Vitali Klitschko has said, while a maternity ward in Odesa has also been targeted.

The drone attack on a maternity ward and medical facilities in Odesa killed one and injured four, an official said, according to Agence France-Presse.

In the capital, emergency services were called to four districts a couple hours after midnight on Tuesday, Klitschko said on the Telegram messaging app.

The latest attacks come after Russia's biggest drone strike on Ukraine on Monday, which Moscow said were retaliatory measures for Ukraine's recent attacks inside Russia.

After Ukraine's "Operation Spider Web" last week, US President Donald Trump called Vladimir Putin, and said the Russian president had promised to respond "very strongly" to Ukraine's attacks.

Air raid alerts are in place across large parts of Ukraine, the country's official air aid map shows, including the Dontetsk, Luhansk and Kharkiv regions in the east.
