DAMASCUS (Dispatches) – An explosion shook the base of an Al-Qaeda-linked terrorist group in northern Syria on Tuesday, killing and wounding dozens of terrorists, sources said. It wasn’t immediately clear what caused the explosion at the base of Hayat Tahrir al-Sham terrorist group in the northwestern province of Idlib, the last major stronghold in the country. The Britain-based so-called Syrian Observatory for Human Rights said the explosion near the village of Ram Hamadan was either an accident during training or a drone strike. It said 20 terrorists were killed or wounded in the explosion.
