The Wikipedia article of the day for April 17, 2018 is Murder of Yvonne Fletcher.
Yvonne Fletcher was fatally wounded on 17 April 1984 by a shot coming from the Libyan embassy on St James’s Square in London. She had been deployed as a constable of the Metropolitan Police to monitor a demonstration against the Libyan leader Muammar Gaddafi. During the protest, two unknown gunmen opened fire with Sterling submachine guns, killing Fletcher and wounding eleven Libyans. The inquest found that she was “killed by a bullet coming from one of two windows on the west side of the front on the first floor of the Libyan People’s Bureau”. After an eleven-day siege of the embassy, those inside were expelled from the United Kingdom, and diplomatic relations with Libya were severed. In 1999 a warming of diplomatic relations with Britain led to the payment of compensation and a statement from the Libyan government admitting culpability in Fletcher’s shooting. British police continued their investigation until 2017, but no one has been convicted of Fletcher’s murder.
