Britain's Queen Elizabeth II has made a tour of New York. She visited the United Nations headquarters and paid her respects to the thousands who died in the September 11th attacks.
The 84-year-old British monarch addressed the UN General Assembly and said the world has dramatically changed since her last visit to the UN in 1957. She praised the UN's aims and values. But, she says the world is still challenged by the achievement of the Millennium Development Goals, and struggles against terrorism and climate change.
UN Secretary-General Ban Ki-moon said the queen is an anchor for our age. Her reign spans the decades from the challenges of the Cold War to the threat of global warming. Afterwards, she visited the site of the World Trade Center, placing a wreath at the site of the attacks, and spent time with victims' families and first responders.
