In the aftermath of the massacre at Houla last month, initial reports said some of the 49 children and 34 women killed had their throats cut. In Damascus, Western officials told me the subsequent investigation revealed none of those found dead had been killed in such a brutal manner. Moreover, while Syrian forces had shelled the area shortly before the massacre, the details of exactly who carried out the attacks, how and why were still unclear. Whatever the cause, officials fear the attack marks the beginning of the sectarian aspect of the conflict.

In such circumstances, it's more important than ever that we report what we don't know, not merely what we do. In Houla, and now in Qubair, the finger has been pointed at the shabiha, pro-government militia. But tragic death toll aside, the facts are few: it's not clear who ordered the killings - or why.
