The Israel-Syria Armistice Agreement provided for a demilitarized zone (DMZ) in the Hula Lake area at the foot of the Golan Heights, a zone which encompassed the area of Palestine as defined in the League of Nations Mandate occupied by Syrian forces at the time of the armistice. Civilian construction and land use in the DMZ caused numerous incidents around this time due to disputes over land ownership even though UNTSO was tasked with attempting to regulate activities leading to such disputes in the zone. After heavy fighting broke out between Israel and Syria in the DMZ, the Security Council in Resolutions 92 (1951) and 93 (1951) of 8 and 18 May 1951 called upon the parties to cease fighting and endorsed the request of the Chief of Staff of UNTSO that the Israeli company involved be instructed to cease all operations in the DMZ until such time as an agreement is arranged through the Chairman of the MAC for continuing its project. In Resolution 111 (1956) of 19 January 1956, the Security Council dealt with the confrontation which had escalated following interference by the Syrian authorities with legitimate Israeli activities on Lake Tiberias. It condemned as "in no way justified" the Israeli action taken in response to that interference in the form of an attack by Israeli regular army forces against Syrian regular army forces on Syrian territory. It also noted that in violation of the provisions of the General Armistice Agreement concerning the DMZ, the Zone had been crossed by the Israeli forces that entered Syria.
