Amnesty International says the United Arab Emirates has secretly armed rebel groups in Yemen with advanced weapons bought from the US.
The rebel groups include the Giants, the Security Belt and Elite Forces which are trained and funded by the UAE.
US commanders say there's no authorisation for the re-direction of the arms.
The UAE hasn't commented on the reports.
Will the furore over the findings push the US Congress to force the Trump administration to withdraw support to the Saudi-Emirati led coalition at war in Yemen?
