LONDON - The state funeral for Queen Elizabeth II took place in London on Monday, with some 500 leading figures from around 200 countries and territories reportedly attending, including the Japanese emperor and empress.

With U.S. President Joe Biden and other world leaders in attendance, local reports said more than 10,000 police officers were mobilized, making it one of the country's largest-ever security operations for a single event.

Buckingham Palace did not make public a list of funeral attendees, but Reuters and other media said some 2,000 people attended.
