In one of the videos, according to the caption, individuals, who are purportedly plainclothes IRGC personnel, open fire and launch tear gas canisters at protesters at a Tehran university. 

In another video, a military vehicle is seen accelerating and purposely ramming into a protester. In addition, protesters can be heard chanting "Death to the dictator!" and "Death to Khamenei!"
