Syrian militant opposition have recently received new weapons that could "change the course of the battle" against the Syrian government.

Syrian rebels have recently received new weapons that could "change the course of the battle" against the Syrian government, a spokesman for the Free Syrian Army told Agence France Presse on Friday.

The so-called "Friends of Syria" group of countries that support the militant insurgents is expected to announce in Doha on Saturday that it will arm the opposition, FSA media and political coordinator spokesman Louay Muqdad said.

"We've received quantities of new types of weapons, including some that we asked for and that we believe will change the course of the battle on the ground.

"We have begun distributing them on the front lines, they will be in the hands of professional officers and FSA fighters," he said.

He did not specify what weapons had been received or when they had arrived, but added that a new shipment was expected in the coming days and recalled that the insurgents had asked for "deterrent weapons".

"That means anti-aircraft weapons, anti-tank weapons, as well as ammunition," he said.

An opposition source, speaking on condition of anonymity, said the system was "Russian-made" but declined to say which country had supplied it.

"The weapons will be used for one objective, which is to fight the regime of (President) Bashar al-Assad," Muqdad insisted.

"They will be collected after the fall of the regime, we have made this commitment to the friends and brotherly countries" that supplied the arms, he said.

Saturday's ‘Friends of Syria’ talks in Qatar will be attended by ministers from Britain, Egypt, France, Germany, Italy, Jordan, Qatar, Saudi Arabia, Turkey, the United Arab Emirates and the United States.

They are expected to discuss military help and other aid for mercenaries in Syria after the latest military gains achieved by the national army on ground.
