United Nations Disengagement Observer Force in the context of Israeli invasion of Syria (2024–present)

Mount Hermon (/ˈhɜːrmən/ HUR-mən) is a mountain cluster constituting the southern end of the Anti-Lebanon mountain range. Its summit straddles the border between Syria and Lebanon and, at 2,814 m (9,232 ft) above sea level, is the highest point in Syria and the Israeli-occupied Golan Heights.

On the top, in the United Nations buffer zone between Syrian and Israeli-occupied territories, is the highest permanently manned UN position in the world, known as "Hermon Hotel", located at 2,814 metres (9,232 ft). The southern slopes of Mount Hermon extend to the Israeli-occupied portion of the Golan Heights, where the Mount Hermon ski resort is located with a top elevation of 2,040 metres (6,690 ft).

Following the fall of the Assad regime on 8 December 2024, Israel invaded the buffer zone in southwestern Syria (adjacent to the Israeli-occupied Golan Heights) and has continued to occupy it. Israel also carried out an aerial bombing campaign to cripple the new Syrian Armed Forces, and demanded that it stay out of southern Syria. Israel's government claimed this was to thwart any "potential threat" from post-war Syria.

Israel took advantage of the power vacuum created by the fall of former Syrian president Bashar al-Assad to increase the amount of territory it controlled by several hundred square miles. Israel declared the 1974 Agreement on Disengagement with Ba'athist Syria to be void. Israel initially said this new invasion would be "temporary", but later said it would hold onto the territory for an "unlimited time". Israel also launched extensive aerial and naval strikes on Syrian military targets across the country, under an operation codenamed Operation Arrow of Bashan (Hebrew: מבצע חץ הבשן, romanized: Mivtza Ḥetz HaBashan). Israel's campaign crippled Syria's military capabilities, including its army and its navy, and destroyed its chemical weapons stockpiles.

The Purple Line was the ceasefire line between Israel and Syria after the 1967 Six-Day War which serves as the de facto border between the two countries. Following the fall of the Assad regime in 2024, Israel broke the Purple Line during its invasion of Syria.

Israel–Syria relations refer to the bilateral ties between the State of Israel and the Syrian Arab Republic. The two countries have been locked in a perpetual war since the establishment of Israel in 1948, with their most significant and direct armed engagements being in the First Arab–Israeli War in 1948–1949, the Third Arab–Israeli War in 1967, and the Fourth Arab–Israeli War in 1973. Additionally, Israeli and Syrian forces also saw relatively extensive combat against each other during the Lebanese Civil War, the 1982 Lebanon War, as well as the War of Attrition. Both states have at times signed and held armistice agreements, although all efforts to achieve complete peace have been without success. Syria has never recognized Israel as a legitimate state and does not accept Israeli passports as legally valid for entry into Syrian territory; Israel likewise regards Syria as a hostile state and generally prohibits its citizens from travelling there, with some exceptions and special accommodations being made by both countries for Druze people residing in Syria and the Golan Heights (regarded by the United Nations as Syrian territory, occupied by Israel since 1967). Israel and Syria have never established formal diplomatic relations since the inception of both countries in the mid-20th century.

In line with the lack of diplomatic relations and continuous state of war, there have been virtually no economic or cultural ties between Israel and Syria, and a limited movement of people across the border. Syria continues to be an active participant in the Arab League's boycott of Israel. Both countries do allow a limited trade of items such as locally-grown apples for the Golan Druze villages, which are located on both sides of the UNDOF ceasefire line, and Syria provides 10 percent of the water supply for the Druze town of Majdal Shams in the Israeli-occupied Golan Heights as a part of an agreement that has been ongoing since the 1980s. The state of peace at the Israel–Syria ceasefire line (which has served as the international border since the 1967 war) has been strained due to the Syrian Civil War, which began in 2011 and ended in 2024.
