KYIV, Ukraine (AP) — Russian missiles and drones killed at least eight civilians and injured 35 others in Ukraine on Monday in what Ukrainian President Volodymyr Zelenskyy described as “horrific attacks.”

Since Russia launched its all-out invasion of its neighbor more than four years ago, its forces have conducted strategic bombing in an effort to destroy the country’s infrastructure and sap Ukrainian morale. More than 16,000 Ukrainian civilians have been killed, according to the U.N.
