Ghouta, Syria — As the machinery for a U.S.-led military intervention in Syria gathers pace following last week’s chemical weapons attack, the U.S. and its allies may be targeting the wrong culprit.

Interviews with people in Damascus and Ghouta, a suburb of the Syrian capital, where the humanitarian agency Doctors Without Borders said at least 355 people had died last week from what it believed to be a neurotoxic agent, appear to indicate as much.

The U.S., Britain, and France as well as the Arab League have accused the regime of Syrian President Bashar al-Assad for carrying out the chemical weapons attack, which mainly targeted civilians. U.S. warships are stationed in the Mediterranean Sea to launch military strikes against Syria in punishment for carrying out a massive chemical weapons attack. The U.S. and others are not interested in examining any contrary evidence, with U.S Secretary of State John Kerry saying Monday that Assad’s guilt was “a judgment … already clear to the world.”

However, from numerous interviews with doctors, Ghouta residents, rebel fighters and their families, a different picture emerges. Many believe that certain rebels received chemical weapons via the Saudi intelligence chief, Prince Bandar bin Sultan, and were responsible for carrying out the dealing gas attack.

“My son came to me two weeks ago asking what I thought the weapons were that he had been asked to carry,” said Abu Abdel-Moneim, the father of a rebel fighting to unseat Assad, who lives in Ghouta.

Abdel-Moneim said his son and 12 other rebels were killed inside of a tunnel used to store weapons provided by a Saudi militant, known as Abu Ayesha, who was leading a fighting battalion. The father described the weapons as having a “tube-like structure” while others were like a “huge gas bottle.”

Ghouta townspeople said the rebels were using mosques and private houses to sleep while storing their weapons in tunnels.

Abdel-Moneim said his son and the others died during the chemical weapons attack. That same day, the militant group Jabhat al-Nusra, which is linked to al-Qaida, announced that it would similarly attack civilians in the Assad regime’s heartland of Latakia on Syria’s western coast, in purported retaliation.

“They didn’t tell us what these arms were or how to use them,” complained a female fighter named ‘K.’ “We didn’t know they were chemical weapons. We never imagined they were chemical weapons.”

“When Saudi Prince Bandar gives such weapons to people, he must give them to those who know how to handle and use them,” she warned. She, like other Syrians, do not want to use their full names for fear of retribution.
