Syrian lobby groups in Washington, who only a few weeks ago were expressing hope that the Obama administration might give a green light to the supply of anti-tank and anti-aircraft missiles, said they had now been forced to “take a reality pill” by the US government.

The Telegraph understands that the Syrian Support Group (SSG), the political wing of the Free Syrian Army (FSA), recently presented American officials with a document requesting 1,000 RPG-29 anti-tank missiles, 500 SAM-7 rockets, 750 23mm machine guns as well as body armour and secure satellite phones. They also asked for $6m to pay rebel fighters as they battle the regime. All their requests were rejected.

“Basically the message is very clear; nothing is going to happen until after the election, in fact nothing will happen until after inauguration [Jan 2013]. And that is the same message coming from everyone, including the Turks and the Qataris,” said a Washington lobbyist for the group.
