Syrian artist Mai Skaf died in the French capital of Paris after a heart attack, while others spoke of a mysterious death.
Mai Skaf has been a supporter of protests in Syria since its beginnings in 2011, forcing her to leave the country after being released from detention.
The anti-Syrian Syrians launched the titles "The Revolving Artist", "The Free Artist" and "The Icon of the Revolution".
Hundreds of Syrians and opposition artists in particular, the late artist, have lamented on social networking sites.
Mai Skaf, born in Damascus in 1969, studied French literature at the University of Damascus and participated in many theater, television and film roles.
