The danger of Russian air attacks remained high on Friday, Ukraine's military said, a day after Russian missiles and drones killed at least 11 people in what appeared to be a response to promises by Western allies to supply Ukraine with tanks.
Russian forces trained tank, mortar and artillery fire on more than 60 towns and villages on Thursday in an arc of territory extending from Chernihiv and Sumy regions in the north through Kharkiv region in the northeast and in the focal points of Russian attempts to advance in Donetsk region in the east - Bakhmut and Avdiivka.
