BEIRUT -- The chief of U.N. observers in Syria says his monitors have been blocked by Syrian troops from the site of a new mass killing.

Gen. Robert Mood said in a statement Thursday that some U.N. patrols were also stopped by civilians in the area and that observers have been informed by residents that their safety will be at risk if they entered Mazraat al-Qubair in central Hama province.

Syrian opposition groups say pro-government militiamen killed dozens of people, including women and children, in Mazraat al-Qubair Wednesday night, with some stabbed to death and others burned.

The exact death toll and circumstances remain impossible to confirm. Syria rejected the claims as "absolutely baseless."
