UN observers have arrived at the site in Hama province where Wednesday’s massacre is reported to have taken place.
Activists have claimed that between 50 and 80 people including women and children were either shot or stabbed in the attack.
The monitors are expected to confirm whether the “atrocity” at Mazraat al-Qabeer was as severe as first reported.
There were also claims of charred bodies lying in several houses in the tiny village of about 150 residents.
The UN team had attempted to view the site on Thursday but turned back after being shot at. Their original convoy had been blocked by Syrian forces and residents from nearby villages.
