A major Russian drone and missile attack on civilian areas of Ukraine killed four people and injured at least 27, officials said Tuesday, while Moscow’s army stepped up efforts to break through Ukrainian front-line defenses in what could be the start of an anticipated spring ground offensive.

The bombardment is the second ​time this week Russia has followed a overnight drone barrage ⁠with heavy daytime attacks, a new tactic as Moscow probes ways to ​penetrate Ukraine's air defenses.

Russian strikes across Ukraine killed at least eight people on Friday, April 3, as Moscow steps up a pattern of daytime attacks, raising civilian costs. Ukraine's Air Force intercepted 541 projectiles out of 579 launched;

At least 10 people, including two children, were killed and 16 others were wounded on Saturday by a Russian missile that hit a five-story residential building in Ukraine's second-largest city, Kharkiv, officials said.

(Bloomberg) -- Russia said drone debris struck a foreign-flagged cargo vessel in a bay of the Azov Sea overnight while Moscow’s forces attacked several Ukrainian regions as the war showing no signs of slowing down.
