52 years ago (1971) We said Foreign Secretary Alec Douglas-Home had expelled 105 Soviet diplomats for spying, following the defection of a Russian spymaster who handed over a list of intelligence officers operating in the UK.
Operation Foot remains the biggest mass expulsion of spies by any country in history and made Britain a much harder target for Russian intelligence.
73 years ago (1950) UN troops recaptured the South Korean capital Seoul three months after it fell to communist North Korean forces.
The Korean War lasted three years and by the time it ended in 1953 it had claimed more than two million lives.
66 years ago (1957) During the US civil rights struggle, paratroopers escorted nine African-American children to Central High School in Little Rock, Arkansas, to protect them from racists who objected to integrated schools.
The troops were sent by President Eisenhower after the state refused to accept the 1954 Supreme Court ruling which outlined that racially segregated schools were unconstitutional.
