Damascus, July 21 (RHC)-- Syrian activists have called for massive demonstrations worldwide to condemn recent U.S.-led airstrikes in Aleppo, which claimed the lives of at least 140 civilians.  Organizers of the protest are calling on people around the world in posts published on their Facebook pages on Thursday to take to the streets to protest the deaths of Syrians by U.S. warplanes.

One Facebook page highlighted what it is calling a massacre carried out by the United States and its military allies.  It calls for demonstrations in reaction to the death and destruction in Syrian cities and towns.

The Syrian Foreign Ministry said in statement on Wednesday that French warplanes had struck the village of Tukhan al-Kubra north of Manbij, killing 120 civilians.  Scores of other civilians remain unaccounted for following the attack.

The deaths came a day after a U.S. airstrike killed 20 civilians in Manbij.  Activists on the "Manbij News" page demanded protests in several cities of Turkey, including Istanbul and Ankara.

Syria has been gripped by foreign-backed militancy since March 2011.  UN special envoy for Syria Staffan de Mistura estimates that over 400,000 people have been killed in the conflict.
