Iran  has been using civilian aircraft to fly military personnel and large quantities of weapons across Iraqi airspace to Syria to aid President Bashar al-Assad in his attempt to crush an 18-month uprising against his government, according to a Western intelligence report seen by Reuters.
"This is part of a revised Iranian modus operandi that U.S. officials have only recently addressed publicly, following previous statements to the contrary," said the report, a copy of which was provided by a U.N. diplomatic source.
"It also flies in the face of declarations by Iraqi officials," it said. "Planes are flying from Iran to Syria via Iraq on an almost daily basis, carrying IRGC (Iranian Revolutionary Guard Corps) personnel and tens of tons of weapons to arm the Syrian security forces and militias fighting against the rebels.">>>
