On 29 October 1956, the first day of Israel's invasion of the Sinai Peninsula, Israeli forces attacked "fedayeen units" in the towns of Ras al-Naqb and Kuntilla. Two days later, fedayeen destroyed water pipelines in Kibbutz Ma'ayan along the Lebanese border, and began a campaign of mining in the area which lasted throughout November. In the first week of November, similar attacks occurred along the Syrian and Jordanian borders, the Jerusalem corridor and in the Wadi Ara region—although the state armies of both those countries are suspected as the saboteurs. On 9 November, four Israeli soldiers were injured after their vehicle was ambushed by fedayeen near the city of Ramla; and several water pipelines and bridges were sabotaged in the Negev.
