Ukrainian officials said Wednesday a Russian missile attack hit the southern port city of Odesa overnight, killing four Syrians and injuring several other people. Oleksiy Kuleba, vice prime minister for reconstruction, said on Telegram that the missile struck a cargo ship that was being loaded with wheat set to be exported to Algeria.

The Kremlin didn't comment on the agreement announced Tuesday between the U.S. and Ukraine on the provision of further military support, including intelligence sharing, and the possibility of a ceasefire that Washington backs.
