A massive overnight Russian attack has hit Ukraine's capital Kyiv, killing at least two people and injuring 16, President Volodymyr Zelensky has said. The attack involved 18 missiles and about 400 drones, primarily targeting the capital, Zelensky added.

Major General Thomas M. Suelzer with the Texas National Guard said a remotely piloted aircraft, or drone, was launched out of Houston Sunday to help with rescue and recovery. The MQ-9 Reaper is operated out of Houston and provides reconnaissance to the search and rescue teams.

The early attempt at drones in World War II saw the Army Air Forces convert B-17 bombers into remote-controlled flying bombs.
