Two people were killed and at least 14 wounded when a Russian drone smashed into a residential high-rise in Ukraine's Black Sea city of Odesa, authorities said on Saturday.

The U.N. Human Rights Monitoring Mission in Ukraine said in a report published Thursday that short-range drone attacks killed at least 395 civilians and injured 2,635 between the start of the war and last April. Almost 90% of the attacks were by the Russian armed forces, it reported.

Russia and Ukraine exchanged more long-range drone attacks that have become a staple of the more than three-year war, officials said Friday, as Russian President Vladimir Putin said Moscow is ready for a fresh round of direct peace talks in Istanbul.
