In Jordan, where the ruling family have been close friends of Britain's royals for decades, King Abdullah II said: "Jordan mourns the passing of an iconic leader.
"Her Majesty Queen Elizabeth II was a beacon of wisdom and principled leadership for seven decades.

This year the queen celebrated her platinum jubilee and made history as the only British monarch to reach the 70-year milestone.
Her ties with the UAE date back decades.
On February 24, 1979, the royal yacht Britannia carried Queen Elizabeth on her first state visit to the UAE, just over seven years after the union was formed in December 1971.
Sheikh Zayed then paid a state visit to Britain in 1989, and two decades later the queen returned to the UAE in 2010.
More recently, the late President Sheikh Khalifa visited her majesty in the UK in 2013.
