In 1955, it is reported that 260 Israeli citizens were killed or wounded by the fedayeen. Some believe fedayeen attacks contributed to the outbreak of the Suez Crisis; they were cited by Israel as the reason for undertaking the 1956 Sinai Campaign. Others argue that Israel "engineered eve-of-war lies and deceptions... to give Israel the excuse needed to launch its strike", such as presenting a group of "captured fedayeen" to journalists, who were in fact Israeli soldiers.
