"The European Union's decision exposes... its obstruction of international efforts to achieve a political settlement to the crisis in Syria," the foreign ministry said in a statement published by state news agency SANA.

The statement also criticized EU’s support and encouragement to terrorists by providing them with weapons in clear violation of international law and the UN charter.

It comes after the EU decided to lift an arms embargo on the anti-government insurgents, opening the way for individual member states to supply weapons to the militants.

Western countries have already been supplying insurgents with what they call “non-lethal” equipment but the new decision marks a turning point in EU's support of the militants.

Extremist groups have swelled the ranks of insurgents in Syria and EU’s decision to arm them will lead to further insecurity which may come to haunt the West on their own doorsteps.

Russia expressed disappointment by EU leaders saying that their move is going to harm peace efforts.
