Russian drones pummeled the Ukrainian Black Sea port city of Odesa, injuring three people and sparking massive fires, officials said Friday, an attack that underlined Moscow's intention to pursue aerial strikes even as it agreed to temporarily halt strikes on energy facilities.

Russian forces launched a mass drone attack on Ukraine's Black Sea port of Odesa late on Thursday, injuring three people and damaging a high-rise apartment building and a shopping centre, the regional governor said.
