July 22, 1946: The Zionist militant group Irgun bombs the King David Hotel in Jerusalem, the headquarters of the British Mandate Secretariat in Palestine. A total of 91 people were killed. The Irgun were led by Menachem Begin, who was subsequently Prime Minister of Israel from 1977 to 1983.
Wikipedia describes the events in more detail. The Times' reportage of the outrage in 1946 can be read in a PDF of page five of the July 23, 1946 edition. Sixtieth anniversary commemorations are taking place this week in Jerusalem, and have been condemned by the British Ambassador to Israel and its Consul-General in Jerusalem.
Uncle George Galloway has had a spray on the topic in today's Guardian.
