Ethiopian Air Force Mi-17V-5 being operated for the United Nations Interim Security Force for Abyei (UNISFA) crashed inside the UNISFA compound. The aircraft was on routine operation carrying Ethiopian troops on rotation from Kadugli to Abyei, and it could be assumed it was intending to land in that compound when it experienced some sort of difficulty and came down in the wrong place. The helicopter hit the ground very heavily and came to rest upright, breaking the tail boom in two and all main rotor blades losing most of their length. An alarming video shows rescuers going in and pulling at least one person out while the main rotor head continues to turn under power.
Of the total 23 on board, three died in the accident and ten passengers were injured with three in critical condition.
NOTE – Registration being wrongly quoted (including by the UN here) as UNO370P, which is the UN operational code and not the registration. The military registration/serial carried on this helicopter was ET2015, per this image.
