Assad forces kill 169 people across Syria

The organization said that 105 had died in Aleppo, 35 in Damascus, 11 in Hama, eight in Daraa, four in Quneitra, two in Deir az-Zor and Homs and one each in Lattakia and Idlib.

SNHR claimed 24 of the dead had been tortured by regime forces, and many of them died in Syrian regime forces' barrel bomb attacks on opposition-held regions. 

Meanwhile, the Local Coordination Committees of Syria reported that Syrian army helicopters had dropped 40 barrel bombs on Aleppo, killing and wounding dozens of people.

During the attacks, many buildings were damaged and demolished, said Ahmed Mohammed Ali, the media manager of Local Coordination Committees of Syria (LCC).

He added that efforts were in process to rescue people from the wreckage.

Islamic Front forces clashed with the Assad regime in southern Aleppo and with the Islamic State of Iraq and the Levant (ISIL) in the north, he stated.

The Islamic Front is the largest alliance of rebel groups fighting the regime, while the ISIL is an Islamist insurgent group that pledged allegiance to al Qaeda in 2004.
