Jordan has opened its skies to Israel so that it can monitor the situation in war-torn Syria, Western intelligence sources told a French newspaper.

The report published Monday by the French daily Le Figaro said two air corridors — one in the south of Jordan and another north of Amman — have been made available to the Israeli air force.

Le Figaro quoted a Western military source as saying that Israeli drones fly at night to avoid detection. The source added that “the Syrians have Russian air defense assets, but Israeli aircraft are difficult to detect and therefore virtually immune to anti-aircraft measures.”

According to the source, the unmanned aircraft are carrying out surveillance, but “they are also armed and therefore can hit targets anywhere in Syria.”

According to the report, Jordan’s King Abdullah decided to permit Israel to use his country’s airspace after meeting with U.S. President Barack Obama in Jordan in March.
