Syria’s main opposition bloc urged the U.N. Security Council on Saturday to convene an emergency meeting to examine what it called an army massacre near Homs, where it said 110 people were killed.

“More than 110 people were killed (half of whom are children) by the Syrian regime’s forces” in the village of Houla, the Syrian National Council said in a statement.

“Some of the victims were hit by heavy artillery while others, entire families, were massacred,” said the statement by Bassma Kodmani, the council’s head of foreign relations.

The Syrian National Council (SNC ) in its statement urged the U.N. Security Council “to call for an emergency meeting to examine the situation... and to determine the responsibility of the United Nations in face of such mass killings, expulsions and forced migration from entire neighborhoods.”

Rami Abdel Rahman, head of the Syrian Observatory while giving the lower death toll, agreed that this was “a real massacre” and complained that “U.N. observers are just staying silent” on the matter.
