Cameron condemns 'brutal and sickening' Syria massacre David Cameron today condemned as "brutal and sickening" another alleged massacre by a Syrian government militia. Mr Cameron, speaking during a visit to Norway, called for "concerted action" from the international community. Syrian government forces were today accused by opposition groups of carrying out a new massacre in the central Hama province. The death toll and circumstances of the killings are as yet unknown. Reports of the massacre, including images, have spread through social networking sites Twitter and Facebook - but are not yet verified. The Britain-based Observatory for Human Rights claim the killings took place overnight in Mazraat al-Qubair - they are alleging that 'dozens' of people were killed. Opposition groups in Syria are claiming that pro-government forces have killed 86 people in Qubair and Maarzaf in Hama province, many of them women and children. They are also claiming the pro-government militia group Shabiha first shelled the farming area and then ten people went in and killed the residents there. The opposition groups claim some of those killed were stabbed to death while other bodies have been burned. The Syrian government denied the reports calling them 'absolutely baseless'. The violence comes after the horrific massacre in late May in a cluster of villages in central Homs province, which left more than 100 dead, including many children and women gunned down in their homes.
