Syrian forces have fired mortar shells at a farming village in the country's north, killing at least seven people, many from the same family, according to activists.
In one video posted online, a bearded man storms into a clinic and yells: "Film me! Film me!"
Counting on his fingers, he says the attack killed his mother, sister, two of his brothers and a nephew.
"That's my son!" he says, pointing to a wounded boy with white bandages on his legs, arms and back. "That's my brother and that's my nephew!" he says, pointing to a body on the floor in a pool of blood and another on a gurney.
The fresh violence in the village of Mishmishan underlines the continual unravelling of a UN-brokered ceasefire that was supposed to begin on April 12 but has never taken hold. The truce is part of a peace plan brokered by international envoy Kofi Annan to allow for talks by all parties on a political solution to the country's conflict.
The UN says more than 9,000 people have been killed since an uprising against President Bashar Assad began in March 2011, prompting a brutal crackdown by government forces.
The shelling of Mishmishan, an agricultural area near the border with Turkey, also highlights the huge challenge facing a 16-person UN team that is trying to monitor the truce in Syria, where violence is widespread and often in relatively isolated areas.
Video posted online of a funeral in Mishmishan showed hundreds of people marching through the village, then lining up to pray over the bodies, which lie in the back of three white pick-up trucks. The videos list seven dead.
Rami Abdul-Rahman, head of the British-based Syrian Observatory for Human Rights, said 10 people were killed in the attack, seven of them when a mortar fell on their house. The three others died elsewhere in the village, he said.
Activist claims and videos could not be independently verified. The Syrian government rarely comments on specific events in the country and bars most media from independent reporting - despite agreeing to do so in accepting Mr Annan's plan.
