US says visit of senior Quds force official is “strongest indication” that Iran supplies Assad with weapons, AFP reports.

“We are confident that he was received at the highest levels of the Syrian government, including by President Assad,” the official said on condition of anonymity. “The US government believes Iran has supplied Syria with munitions” for use in the military crackdown.

The United States has long suspected Iran of supplying Damascus with weapons as Assad struggles to cope with mass protests against his rule.

Earlier in the week, Turkish customs officials intercepted four trucks suspected of carrying military equipment from Iran to Syria.

Iran officially denied reports about arms shipments to Syria. A statement by the Iranian embassy in Turkey obtained by CNN Friday stated: “We deny such claims and we would like to state that the Islamic Republic of Iran sees people’s demands to be paid attention to as a way of providing domestic security and stability and believes that dialogue between the Syrian government and the opposition is the way out from the current situation.”
