Aircraft alarms have sounded all over Ukraine on Monday, and according to The Guardian, over 100 robots have been fired at the country.
The attacks, like previous attacks, appear to have been aimed at civilian infrastructure, AP reports.
During the day, several residents of Kyiv have sought shelter in the city's subway.
