Russian air strikes targeted a truck in a humanitarian mission as it was delivering aid to Syria in the town of Azaz in northwest Syria, the truck's driver said on Monday.
The driver, Murat Muvaz, who was sent to a hospital in Kilis in southern Turkey after the attack, said the Russian airplane targeted civilians in Azaz on Monday.
"We heard the sound of planes while we were waiting near our vehicles with other drivers," he told Anadolu Agency.
"When the first missile struck we started to run around. We do not know who died and who survived. Everybody ran away in panic. Some people fell on the ground. The plane came back one more time and struck [with] another missile, then the trucks caught fire."
At least six people were killed in the Russian attack and more than 18 wounded.

Muvaz added, "I would like to ask that what our crime is. We are unarmed. What did the drivers do to you? Russia is striking civilians on the excuse of counter-terrorism. DAESH’s area is known. If you are going to hit, go and hit them."
Ten trucks were reported to have been burnt in the incident as they were parked 5 kilometers away from the town of Azaz.
The incident comes a day after Russian jets bombed a bakery built by a Turkish humanitarian aid foundation in the city of Idlib, northwestern Syria.
The bakery was established 16 months ago by the Turkish Humanitarian Relief Foundation (IHH).
About 65,000 loafs of bread were reported to have been produced in the bakery each day, serving at least 40,000 people, the foundation’s officials stated.
Another aid convoy was targeted by the Russian warplanes on November 25, killing seven drivers. Twenty trucks which were carrying humanitarian aid were burned.
Russian has conducted an aerial campaign in support of Syrian regime leader Bashar al Assad since September 30 targeting opposition forces, while Russia said its war planes are targeting DAESH.
Moreover, the US has accused Russia of targeting US and Turkey trained opposition groups.
