Following US claims that Iran is sending weapons to Syria via Iraq’s airspace, Baghdad has requested Washington provide evidence for the allegations.

Iraqi spokesman Ali al-Moussawi said Iran is transporting supplies through Iraq’s airspace, adding that Tehran has assured Prime Minister Nouri al-Maliki that the flights contain humanitarian aid for victims of Syria's unrest.

Al-Moussawi said the US has promised to provide evidence for their allegations against Iran.

This is while the US and its allies have openly advocated supplying Syrian insurgents with weaponry, and have been supporting the rebellion since the beginning of unrest.

On August 1, spokeswoman of the UN observer mission in Syria Sausan Ghosheh said armed groups fighting against the government in the northern city of Aleppo were equipped with heavy weapons, including tanks.

Britain’s Foreign Secretary William Hague admitted on September 4 the British government has authorized “limited contacts” between the UK agents and representatives of the so-called Free Syrian Army.

Hague also confirmed that London has provided “an extra £5 million in non-lethal practical assistance to help protect rebel groups and so-called human rights activists in Syria.”

Syria has been the scene of violence by armed groups since March 2011. The violence has claimed the lives of hundreds of people, including many security forces.
