Israeli–Syrian ceasefire line incidents during the Syrian Civil War

Several Israeli–Syrian ceasefire line incidents took place during the Syrian Civil War, straining the relations between the countries. The incidents are considered a spillover of the Quneitra Governorate clashes since 2012 between Syrian Army and the rebels, ongoing on the Syrian-controlled side of the Golan. Through the incidents, which began in late 2012, one Israeli civilian was killed and at least 4 soldiers wounded; on the Syrian controlled side, it is estimated that at least ten soldiers were killed, as well as two unidentified militants, who attempted to penetrate into Israeli-occupied side of the Golan Heights.

Timeline
Israel was first involved on 11 November 2012, when mortar shells from Syria landed near an Israeli military outpost in the Israeli-occupied Golan Heights, responding by firing "warning shots" into Syria. This accounted for the first direct cross-border incidents between the two countries since the Yom Kippur War nearly forty years prior.

On 11 November 2012, a stray mortar shell from fighting in Syria's Quneitra Governorate landed near an Israeli military outpost in the Golan Heights. Israel responded with a "warning shot" and released a statement warning further retaliation if the attacks persist.

On 17 November 2012, there was another incident where Syrian army fire hit an IDF patrol near the DMZ, damaging one jeep although no injuries were reported. Israeli artillery responded by shelling the army position and Syrian army fired back with mortars. Israel confirmed a direct hit on the source of fire and said that Syrian soldiers may have been killed by the incident.

On 25 November 2012, clashes between rebels and the army resulted in stray bullets striking near an IDF vehicle driving along a fence at the Israeli border with the DMZ. No injuries or damages were reported, and Israel did not retaliate.

On 24 March 2013, the IDF fired a guided missile at a Syrian machine gun nest after Israeli troops were shot at twice in the Golan Heights. No Israeli soldiers were hurt in the shooting, during which army vehicles were hit.

On 18 March 2014, an Israeli jeep traveling on the Golan Heights near the Syrian border came under attack, when an explosive device was detonated in its vicinity. One soldier was seriously wounded. Another three soldiers sustained light-to-moderate injuries. IDF 155 Artillery battery returned fire across the border following the incident and shot several shells on a Syrian outpost. Israel also responded by carrying out multiple airstrikes against Syrian targets, including a military headquarters, artillery batteries and a training base of the Syrian army. The Syrian army reported that the Israeli airstrikes killed one Syrian soldier and wounded seven. this happened after a few days after a similar incident in the Israeli-Lebanese border when another jeep landed on an exlosive cargo and Israel responded with artillery and tanks fire towards Lebanon. Israel blamed Hezbollah for both incidents.

On 28 March 2014, Israeli soldiers opened fire on two gunmen seen attempting to sabotage the border fence with Syria on the Golan Heights. IDF said both armed suspects were struck by the gunfire.

On 4 June 2014, two mortar shells were fired from Syria into the Israeli-occupied Golan. The Iron Dome missile defense system was activated for the first time in northern Israel to intercept the two shells. At least two intercepting missiles were fired towards the Syrian ceasefire line, but were "called off" in-flight by the Iron Dome's operators when it was made clear the shells were going to fall in open fields. The falling shells caused fires in several spots in the area, but firefighters were called at the scene and put out the fires.

Reactions
🇮🇱 Israel – On 12 November 2012, Israeli prime minister Benjamin Netanyahu said "we are closely following the events and will respond accordingly," and that Israel "won't allow its borders to be breached or its citizens to be fired upon."

On 6 January 2013, Netanyahu announced that the Israeli army would be building an improved security fence in the border between the Israeli-occupied and sovereign Syrian zones of the Golan Heights. He stated that the Syrian army had largely "backed off" from the area, leaving it in control of "global jihad operatives" and that the fence would protect Israeli territory from "infiltrations and terror". An Israeli security official stated that around 10 km of the fence had already been completed, with approximately 60 km remaining.

Syria – On 13 November 2012, the Syrian government, through the United Nations Disengagement Observer Force (UNDOF), pledged to halt firing toward Israeli territory.

Syrian opposition – Turkey's Anadolu news agency reported that the Free Syrian Army released a statement accusing Israel of attempting to "aid Assad's criminal regime" by firing into Syria.
