Government forces have taken a village on the edge of a large ceasefire zone encompassing rebel-held territory in north-west Syria, according to activists.
The government pushed opposition fighters out of the village of Zalaqiyat in Hama province, following days of fighting that killed at least 14 rebels, activists said.
Russia, Turkey and Iran agreed on Friday to enforce a ceasefire between government and opposition forces in four areas in Syria, including one that extends into northern Hama province, where Zalaqiyat lies.
It is not clear if the agreement encompasses the village. Russia said it will publish maps by June 4.
The Britain-based Syrian Observatory for Human Rights said 11 pro-government fighters were killed in the Zalaqiyat advance.
