The reverberations have only just begun following the massacre in Houla. The U.N. Security Council held an emergency meeting Sunday afternoon to discuss what the next steps would be for the international community, and to hear directly from the head of the U.N.'s observer mission in Syria.
In U.N. Secretary-General Ban Ki-Moon's official letter to the U.N., he said the monitors saw "artillery and tank shells, as well as fresh tank tracks." They said "many buildings" had been destroyed by heavy ammunition fire. Locals told them that local pro-government militia, known as "Shabiba" entered the city late at night. He also said the monitors are facing increased pressure in Syria, and even being blamed by some locals for an increase in violence in the country.
The Security Council released their official joint statement condemning the attacks, and urging both sides to cease the use of heavy weapons in populated areas. They attributed the heavy artillery shells and tank shells to the Syrian government, but didn't go so far as to announce any new restrictions against Syria. The statement said the Council, "reaffirmed their strong commitment to the sovereignty, independence, unity and territorial integrity of Syria." They said they're going to continue to investigate the incident, and that the U.N. will hold the perpetrators accountable.
