From the BBC:
"The Israeli army was saying: 'This is the Israeli Defence Forces, we are asking all the people to leave their homes and go to the school. Ladies first, then men.'
"We decided to send the women first, two by two," he said.
"The army was about 15 metres (50 feet) away from the house or less. They shot her in the head," he said.
Another family:
"They told us you all have to go to the centre of the town, where the school is.
"We put the women first, and we put our children on our shoulders, with white bandanas on their heads.
"When we were walking, with the women first, they saw soldiers and they started to shout to them, to tell them 'we have children, we have children'. They started to shoot us. My aunt was killed with a bullet in her head."
"We have tried to leave the house during the three-hour humanitarian ceasefire, but we got shot at," he said.
