KYIV, May 18 (Reuters) - The Ukrainian capital Kyiv was under a sustained Russian drone attack early on Sunday, Ukraine's military said.
More than four hours after the air force issued air raid alerts at midnight for Kyiv and most of eastern Ukraine, tens of drones were still in Ukrainian skies and threatening Kyiv and other parts of the country, the air force posted on the Telegram messaging app.
Reuters witnesses in and around Kyiv heard blasts that sounded like air defence units in operation.
