Britain's Prince William and his wife, Kate, arrived in Belize on Saturday for a weeklong Caribbean tour that was marred by a local protest before it even began amid growing scrutiny of the British Empire's colonial ties to the region.

The arrival of the Duke and Duchess of Cambridge coincides with the celebration of Queen Elizabeth's 70th year on the throne, and comes nearly four months after Barbados voted to become a republic, cutting ties with the monarchy but remaining part of the British-led Commonwealth of Nations.

Three miniature cannons fired a salute to the couple as their plane landed in Belize City before a military band played the national anthems of Belize and Britain at a welcoming ceremony that kept the media throng at a distance.
