Russia is increasing production of air defence missiles to address "key issues", defence minister Sergei Shoigu has announced.
The defence ministry released footage of his speech after Ukrainian drone attacks on Russian cities and energy infrastructure.
"There has been a significant increase in the volume of production. We have more than doubled production of the missiles we need for air defence," he said while visiting a missile factory.
"But there are some key issues we need to address and we need to address them quite vigorously. There is the question of engines, and there is the question of the establishment of launcher production."
