Three people have been killed and 35 taken to hospital following an attack by Ukraine on a factory in the city of Izhevsk - more than 1,000km (620 miles) from the border, Russian authorities say.

A Ukrainian drone struck a Russian industrial plant some 1,300 kilometers (800 miles) from Ukraine, a local official said Tuesday, after Ukraine President Volodymyr Zelenskyy prioritized the weapon's development and Russia pounded Ukraine with a monthly record of drones in June.

While repelling the attack, Ukraine lost its fourth F-16 fighter jet. Although details surrounding the loss remain undisclosed, Ukrainian President Volodymyr Zelenskyy posthumously bestowed the title of Hero of Ukraine on pilot Maksym Ustymenko,
