UK Foreign Secretary Liz Truss said:
It was with great sadness that I heard of the death of His Highness Sheikh Khalifa bin Zayed Al Nahyan, President of the United Arab Emirates and Ruler of Abu Dhabi.
He served the United Arab Emirates for many years with dedication. His contribution to regional stability, his personal commitment to global development and his work to bridge gaps between nations in the interests of peace and stability will long be remembered.
I would like to offer my sincere condolences to the United Arab Emirates and its people at this sad time.
