His comments came after activists said at least 42 people, mostly civilians, were killed when unknown war planes attacked a mosque in the village of al Jinneh in western Aleppo, which borders Idlib.
The US military said it struck a meeting of al-Qaeda leaders in northern Syria Thursday night but residents say the strikes killed scores of civilians in prayer, renewing concerns that an aggressive airstrike campaign under the Trump administration is putting more civilian lives in danger. "The death toll may rise in the next few hours", he told ARA News, speaking on condition of anonymity for safety concerns.
A mosque is in the vicinity, he added, but recent satellite imagery shows that building still standing.
"More than 100 people were wounded", he said, adding that many were still trapped under the collapsed mosque in the village of Al-Jineh, just over 30km west of Aleppo.
The US has also carried out strikes there in recent months, targeting a militant rebel group that until previous year was a formal affiliate of al-Qaeda.
A Syrian Civil Defense officials said his organization believes the bombing was carried out by Russian Federation.
A powerful Syrian opposition group and other opposition activists blamed the USA -led coalition for the airstrike. "The goal was a building located across the street from the mosque, which was used to hold meetings by al-Qaida terrorists", she said. It was right after prayers at a time when there are usually religious lessons for men in it.
She continued, "They say that dozens of people were killed in the strike there and that several people are believed to be still alive under the rubble".
Thomas later clarified that the precise location of the strike was unclear, but that it was the same one widely reported to have targeted the village mosque.
The Syrian government and Russian forces have been conducting strikes in the Idlib province and the USA has recently also begun to launch attacks in the area. Critics say the real number is much higher.
