The Queen has said it is “difficult to escape a very sombre national mood” following tragedies in London and Manchester in recent weeks.
Her message comes as residents caught up in the Grenfell Tower fire which killed at least 30 people, condemned the “chaotic” relief effort.
Some say they no longer want Kensington and Chelsea council involved in any way.
The statement from the Queen on her official birthday came after Prime Minister Theresa May pledged to “get to the bottom” of the west London tower block fire.
Mrs May was jeered when she visited the North Kensington estate on Friday, and is facing mounting criticism for her response to the disaster.
The Queen and Duke of Cambridge had earlier met volunteers, residents and community representatives during a visit to the Westway Sports Centre.
She also visited some of those injured in hospital following the bomb at Manchester Arena little under a month ago.
In an unprecedented statement, the Queen said she had been “profoundly struck by the immediate inclination of people throughout the country to offer comfort and support to those in desperate need”.
“Put to the test, the United Kingdom has been resolute in the face of adversity,” she said.
“United in our sadness, we are equally determined, without fear or favour, to support all those rebuilding lives so horribly affected by injury and loss.”- BBC
