Dozens of Syrian children were killed in the Houla attack, which marked one of the deadliest single incidents of the 15-month uprising against Bashar al-Assad. It is widely believed Syrian forces committed the slayings, but that remains unconfirmed. New video emerged on Tuesday from survivors of the massacre blaming Syrian forces and describing the killings of their loved ones.

Woman: “They hit my husband with guns until his brains burst out before they shot him. They killed four of my daughters, my sister-in-law and two of her children, my cousin and her four children, my other sister-in-law and her daughter.”
