An Israeli military spokesperson said that "the IDF (Israel Defense Forces) fired warning shots towards the area using a tank."
According to the spokesperson, the Syrian army forces were observed by the Israeli military watchers "conducting works in order to strengthen a military post in the northern part of the demilitarized zone between Syria and Israel."
Under the 1974 ceasefire agreement between Israel and Syria, entry of heavy construction tools or military vehicles into the demilitarized zone is prohibited.
The incident came a day after the Israeli army fired a shell towards a post of President Bashar Assad's army. A military spokesperson said the fire came after Syrian forces entered the demilitarized zone.
Israel and Syria share a disputed border in the Golan Heights, a territory that Israel seized from Syria in the 1976 Middle East War and annexed it later.
Israel has been carrying out occasion airstrikes against Syrian army position, usually in response to errant fire from the six-year war between the Bashar Assad regime and rebel groups.
