The video shows Sheikh Salafi repeating phrases that are used platforms militant groups chant, such as "Oh God, you Bashar, God Aqsam the back, paralyzing Abdanh, broken ribs," as he's doing this, his chair collapses and he drop to the ground, he's ridiculed and laughed at.
Most of the laughing people were later beheaded.
