Rebels attack a convoy in northern Syria, killing at least one woman and wounding more than a dozen people, according to rights groups.
The video which can not be independently verified comes after Islamist militants warned they would target all vehicles on the one road to Aleppo still in use by the army.
Pulse Gathering for Syrian Civil Youth, which calls itself a non-violent group against sectarianism, said on Facebook that the attack was a quote "a reprehensible crime".
Syrian state media has not mentioned the incident.
