Russian missiles streaked into Kyiv early Thursday in the biggest assault on the Ukrainian capital in weeks, injuring at least 10 people and damaging several residential buildings and industrial facilities, according to local officials.

Serhii Popko, the head of the city military administration, said air defense systems in and around Kyiv had intercepted about three dozen Russian missiles, including ballistic ones. His claim could not be independently verified. Mr. Popko added that no deaths had been reported so far.
