Damascus on Thursday filed a complaint with the United Nations Security Council over Israeli fire into Syrian territory a day earlier.

In a letter to the president of the council and UN Secretary-General Ban Ki-moon, Syria claimed Israel fired at a mosque and a school near the demilitarized zone separating the two countries, injuring seven soldiers and four civilians.

According to Israel Radio, the Syrian Army warned the IDF against attempts to test its capabilities.

Syrian President Bashar Assad on Thursday accused Israel of cooperating with Syrian rebel factions to tip the balance of power in the demilitarized zone.

“The situation in Syria is under control. The danger is elsewhere,” Assad said in an interview. “It lies in the Israeli plan to set up [a fence] near or close to the occupied Golan Heights. They plan for this fence to be under the control of terrorists, in a similar set-up to the one in southern Lebanon by Israeli occupation.”

According to Assad, rebel factions have struck Syrian forces on Israel’s instruction and have been coordinating with Israel in taking positions in the demilitarized zone along the Golan Heights border in order to remove Syrian army forces.

“There’s nothing new in cooperation between the armed groups and Israel,” he said. “Not only in the mutual goals of the outcome of the war, but also in specific operations like fighting against sectors of the Syrian Arab army prepared to confront the Israelis, and also the attacks on air defense sites, occurred through Israeli instructions.”

“Insurgents are flowing in unprecedented numbers from Jordanian territory to Hamma, a demilitarized zone, according to the separation of forces agreement between Syria and Israel,” he said. “An area where forces of Syria or Israel shouldn’t be. But the terrorists have been rounded up in that area for training by request of the occupation, and therefore they represent an extension of [the occupation].”

While Israel has not officially taken sides in the Syrian civil war, Assad’s accusations are not the first from the Syrian government that Israel is involved in the conflict.

In a television interview with a Hezbollah-linked channel late Monday, Syrian presidential adviser Buthaina Shaaban claimed IDF officers were physically present in Syria to monitor the fighting and call in troops to assist the opposition.

Shaaban also called on Jordan to control rebel traffic into Syria.

There have also been a number of incidents where Israel has retaliated against fire from Syrian territory as well as several recent confrontations between Israel and Hezbollah in connection with the Lebanese terror organization’s relationship with Syria and role in the conflict.

On Wednesday, IDF forces spotted and killed two terrorists who belonged to an organization affiliated with Hezbollah trying to plant explosives on the Israel-Syria border in the northern Golan Heights early Wednesday morning, according to the IDF Spokesperson’s office.

Israel has been bracing for a possible Hezbollah attack since the Lebanese Shiite terror group said last Wednesday that it had been hit by Israeli planes near the Syrian border earlier in the week.

Jerusalem has not confirmed involvement in the reported strike, though a high-ranking official told Time magazine that the Israel Defense Forces was behind the attack.

Lebanese sources said that Hezbollah was responsible for firing two Katyusha rockets that struck the Golan Heights on Saturday. The rockets, which hit open areas in northern Israel overnight, were said to be retribution for the strike attributed to Israel near the Lebanon-Syria border last Monday.

Last week, Israel put its own troops on the northern border with Lebanon on high alert, shortly after Hezbollah threatened retaliation.

Hezbollah has acknowledged it was attacked by Israel and warned that it would strike back when and where it deemed appropriate.

The organization’s chief, Hassan Nasrallah, warned key military personnel of the possibility of war with the Jewish state, a Lebanese journalist with close ties to Hezbollah said last week.
