Forsyth said that he met a Syrian family in Lebanon who told their 16-year-old daughter to marry an older man.
“Her mother said she is beautiful and every time the [Syrian] soldiers came to the house, she thought: ‘They are going to rape her,’” he said.
“Rape is being used deliberately to punish people,” he said, adding that girls as young as 14 are being married off.
Save the Children works in neighboring countries and within Syria, but Damascus has restricted access to aid organizations, especially in opposition-held territory.
The charity called for unfettered and safe access for humanitarian agencies, including “access across the lines of the conflict,” and for Damascus to ease bureaucratic restraints.
