Sixty years ago on Monday, a coup in Iran shook the Middle East.
The democratically elected Iranian prime minister at the time, Dr Mohammad Mossadeq, was overthrown, paving the way for Mohammad Reza Pahlavi to return to the country as the Shah.
Now for the first time, the CIA has officially acknowledged its own role in the coup, releasing documents that detail America's hand in the events.
