"They seized two buildings in the provincial capital," the so-called Syrian Observatory for Human Rights director Rami Abdel Rahman said on Friday. The army used these buildings to monitor the city which has been suffering deadly attacks carried out by militants throughout the two-year old bloody conflict in Syria.

The Los Angeles Times reported last week that US special forces were providing training in Jordan to militants in Syria, that included instruction in the use of anti-tank and anti-aircraft weapons.

Washington’s recent military moves in Jordan, near Syria borders, have added to the grave concerns about US government pressing to send arms to insurgents in Syria to crush the army.

In the face of international efforts for a ceasefire in Syria, US secretary of States John Kerry told a conference in Doha that the war should reach to e point where militants compensate their losses first and then be able to start the talks.

The move has been widely criticized by Russia which has been trying for starting negotiations between the Syrian government and opposition to settle their conflict.

Speaking at a Friday press conference in the Moroccan Capital of Rabat, Sergei Lavrov said, "The activities aimed at providing weapons to the opposition, which have recently intensified, only means that the precondition [set by the foreign-backed militants to restore a balance of power on the battle ground] is supported by the West and other countries which are going to supply such weapons, this contradicting the very concept of the conference, which is to begin without any preconditions."

Syria crisis started as pro-reform protests but with interventions by the United States, UK and their regional and Western allies it soon turned to a massive insurgency which took in numerous terrorist groups from all over Europe and the Middle East to wage one of the bloodiest wars the region has ever experienced.

The war, which many fear is turning to a “war of hatred”, has already taken more than 90,000 lives.
