The United Nations Security Council called on Wednesday for Syrian military forces and opposition fighters engaged in the country's civil war to cease "military activity of any kind" in the buffer zone between Syria and Israel in the Golan Heights.

The council urged all warring parties engaged in Syria's three-year conflict to exercise restraint in order to prevent an escalation of tensions and potentially breaching the ceasefire between Israel and Syria.

The 15-member council also resolved to extend until December 31 the UN mission monitoring the ceasefire between the two counties.

On Sunday, an anti-tank missile fired from inside Syria, hit a Israeli civilian vehicle, killing a 14-year-old boy and wounding two others.

Israel responded early on Monday to the cross-border missile attack with air strikes on targets belonging to the Syrian military.

Shelling from the Syrian civil war has often crossed the border onto the Golan, including what Israel has said were deliberate attacks on its military.

While the Syrian army has a presence on the Golan, some areas are controlled by rebels fighting to topple President Bashar Assad, including al-Qaida-inspired radicals such as Jabhat Al-Nusra and ISIS.
