UN-Arab envoy Kofi Annan expressed "horror" at the Houla massacre of more than 100 people as he began a visit to Syria yesterday aimed at salvaging his battered peace plan.
Annan called the "tragic" massacre in the central town "an appalling moment with profound consequences."
The former UN chief said those responsible for the massacre must be held to account, and urged "everyone with a gun" to abide by his six-point blueprint to help end 15 months of bloodshed.

Muallem explained "the truth of what is happening in Syria and the attacks against law and order, which are aimed at sowing chaos, despite the reforms that Syria has adopted in all areas.
