CAIRO: Protesters and journalists reported security forces in Tahrir Square used teargas that caused many protestors to faint last night November 22. Protestors set fire to piles of garbage, thinking the smoke caused by fire could push the gases into the sky. Doctors in Tahrir Square said they cannot identify the type of tear gas used by security forces. A journalist reported the protestors chanted, “People want to executed Tantawi,” referring to chairman of Egypt's ruling military council Hussein Tantawi.
