BEIRUT (AP) — A key activist group is threatening to withdraw from Syria’s main umbrella grouping, saying the council has drifted away from the spirit of the Syrian revolution.

A pullout by the Local Coordination Committees from the Syrian National Council would be a blow for the group. The SNC already is facing political and organizational challenges in its quest to oust President Bashar Assad.

The LCC issued a statement on Thursday accusing the SNC leadership of marginalizing council members and acting alone on major decisions.

It threatened to suspend its membership in the SNC and later withdraw altogether if its concerns are not addressed.

Earlier this week, Burhan Ghalioun was re-elected to a third, three-month term as head of the SNC.
