Russia launched more than a hundred drones at Ukraine overnight and early Friday, killing one person and wounding eight others, officials said.

Desertion is starving the Ukrainian army of desperately needed manpower and crippling battle plans at a key time in its war against Russia's invasion.

Russian forces have launched a major assault on Ukraine, firing missiles on cities and military targets. The invasion by land, air and sea began after a pre-dawn TV address where Russian President Vladimir Putin demanded that Ukraine's military lay down its arms.

The head of Britain's foreign intelligence service said Friday that Russia is conducting a "staggeringly reckless" sabotage campaign against Ukraine's Western allies, and that his spies are working to stop the consequences from spiraling out of control.
