Tens of armed men have been killed or injured in blasts that occurred when explosive charges they were planting in the northern Syrian city of Aleppo detonated accidentally, Press TV reports.
The incident occurred on Tuesday when the rebels were planting the explosive charges in a factory.
Meanwhile, the Syrian Army has cleared most areas of Aleppo of foreign-backed armed groups. The army says it killed tens of rebels in the Salahuddin and al-Sukkari neighborhoods of the city on Tuesday.
Syria has been experiencing unrest since March 2011. Damascus says outlaws, saboteurs, and armed terrorists are the driving factor behind the unrest and deadly violence while the opposition accuses the security forces of being behind the killings.
Western states have been calling for Syrian President Bashar al-Assad to step down. However, Russia and China are strongly opposed to the Western drive to oust Assad.
The Syrian government says that the chaos is being orchestrated from outside the country, and there are reports that a very large number of the armed militants are foreign nationals, mostly from Egypt, Algeria, Saudi Arabia, and Afghanistan.
