Queen Elizabeth II has died, Buckingham Palace announces

Queen Elizabeth II has died at Balmoral Castle in Scotland, Buckingham Palace says. She was the longest-reigning British monarch. She died on Thursday at the age of 96.

Elizabeth ascended to the throne in 1952, on the death of her father, King George VI.

Doctors had become concerned about her health on Thursday.

Queen Elizabeth II ruled over the United Kingdom and 14 other Commonwealth realms, and became one of the most recognizable women ever to have lived. Her son, Charles, immediately became King upon her death.
