On Tuesday, democratic chairman of the Senate’s Foreign Relations Committee, Sen. Robert Menendez, introduced the bill which authorizes the US government to directly back foreign sponsored militant groups with arms.

The bill, which also authorizes a 250-million dollar fund to help the transition of the Syrian government, was supported by both the Democrats and Republicans with a 15-3 vote.

The decision comes as in recent days Syrian army has been making considerable advancements in key areas, especially the strategic town of al-Qusayr, raising hopes for cutting one of the main routes of arms supply to the terrorist groups.
 

The move is likely to fire the flames of war in Syria with several terrorist groups including al-Qaeda and al-Nusra Front fighting against the government and to affect the long-awaited talks between the Syrian government and opposition groups for finding a way to end the crisis which has taken thousands of lives.

US Sen. Mark Udall (D., Colo.) warned his fellow senators of the dangers of arming rebel forces whose intentions are unknown, saying "I think we have to ask the question, who are we arming?”

“To tell you the truth, I don't think we know who we're arming. The truth is it changes every day," he added.
