Is it older than Israel?

The King David Hotel in Jerusalem housed the British Mandate's secretariat and military headquarters in its southern wing. On 22 July 1946 the Irgun, dressed as Arab workers, carried milk churns packed with explosives into the basement kitchen. The bombs went off at 12:37 and brought down the wing. Ninety-one people were killed: 41 Palestinians, 28 Britons, 17 Jews and five others, most of them clerks and typists.

The Irgun said it had telephoned a warning; the British said none reached anyone who could act on it in time. The Haganah, which had approved the operation as part of the joint Jewish Resistance Movement, distanced itself afterwards. Menachem Begin, who ordered it, became prime minister of Israel in 1977.
