Ukraine strikes psychological blows in drone warfare over Crimea

Experts such as Justin Bronk from the Royal United Services Institute thinktank suggest the drone in the film could have been a commercially available Chinese-made model, the $9,500 (£8,030) Mugin-5, or a copy of it. It has a flying time of up to seven hours, the manufacturers say, and a top speed of 150 km/h (95mph) and could have been adapted to carry an improvised warhead. The payload, the manufacturers say, is 15 to 20 kilograms.
