The Washington Post reports: A surge of rebel advances in Syria is being fueled at least in part by an influx of heavy weaponry in a renewed effort by outside powers to arm moderates in the Free Syrian Army, according to Arab and rebel officials.

The new armaments, including anti-tank weapons and recoilless rifles, have been sent across the Jordanian border into the province of Daraa in recent weeks to counter the growing influence of Islamist extremist groups in the north of Syria by boosting more moderate groups fighting in the south, the officials say.

The arms are the first heavy weapons known to have been supplied by outside powers to the rebels battling to topple President Bashar al-Assad and his family’s four-decade-old regime since the Syrian uprising began two years ago.

The officials declined to identify the source of the newly provided weapons, but they noted that the countries most closely involved in supporting the rebels’ campaign to oust Assad have grown increasingly alarmed at the soaring influence of Islamists over the fragmented rebel movement. They include the United States and its major European allies, along with Turkey and the United Arab Emirates, and Saudi Arabia and Qatar, the two countries most directly involved in supplying the rebels. Security officials from those nations have formed a security coordination committee that consults regularly on events in Syria, they said.

Although the Obama administration continues to refuse to directly arm the rebels, the administration has provided intelligence assistance to those who are involved in the supplies, and it also helps vet opposition forces. U.S. officials declined to comment on the new armaments.

The goal of these renewed deliveries, Arab and rebel officials said, is to reverse the unintended effect of an effort last summer to supply small arms and ammunition to rebel forces in the north, which was halted after it became clear that radical Islamists were emerging as the chief beneficiaries.

“The idea was to get heavier stuff, intensify supply and make sure it goes to the good guys,” said an Arab official who spoke on the condition of anonymity because of the sensitivity of the operation. “If you want to weaken al-Nusra, you do it not by withholding [weapons] but by boosting the other groups.”

Louay al-Mokdad, the political and media coordinator for the Free Syrian Army, confirmed that the rebels have procured new weapons donated from outside Syria, rather than bought on the black market or seized during the capture of government facilities, the source of the vast majority of the arms that are in the hands of the rebels. But he declined to say who was behind the effort. [Continue reading…]
