A Syrian monitoring group, quoting local activists, said Friday that an incendiary bomb struck outside a school in northern Syria earlier this week, killing one man and injuring at least seven people.
Amateur video posted online showed several teenage boys and young men, some stripped down to their underwear, with burns over their bodies in a makeshift clinic. Some were moaning in agony.
A doctor speaking in one of the videos said seven people were killed and about 50 wounded. She also said that the bomb carried an incendiary substance.
"The strike hit the school not far from here," she said. "It was something similar to chemicals, maybe similar to napalm that causes big burns."
The most seriously wounded were taken to nearby Turkey, the doctor said. She gave her first name, Rula, and said she works for the Britain-based charity Hand in Hand for Syria.
The Syrian Observatory for Human Rights, a Britain-based group linked to a network of anti-regime activists, said the attack took place Monday in the community of Urum al-Kubra in the northern Aleppo district. Rami Abdel-Rahman, the head of the Observatory, said local activists confirmed one dead and seven wounded in the attack.
Amateur video showed a bomb crater near the outer wall of a building that served as a school.
The BBC filmed the area shortly after the attack and interviewed survivors.
