A Russian drone strike on Ukraine's second-largest city killed two people and wounded 35 late on Saturday, officials said, as President Volodymyr Zelenskiy urged Kyiv's partners to respond to such attacks while seeking peace in the three-year-old war.

The U.S. reached deals with Ukraine and Russia to pause their attacks over the Black Sea and against each other's energy targets, but it was not clear when and how the deals would come into force.
