Ukrainian defence official Yevgeny Silkin said Shahed-136 kamikaze drones are made of plastic and other non-frost-resistant materials. The claims come as the Ukrainian military has not reported any use of the Iranian drone since November 17. However, there is another reason according to UK’s MoD why Putin is not using the Iranian drone. Watch the video to find out about it.
