CAIRO: Egyptian military police forces gathered around the Ministry of Interior on Monday to secure it from the masses of protesters heading towards the ministry. In response, protesters acted as human shields on Mohamed Mahmoud Street to separate the security forces from other protesters and avoid further clashes. Military police closed all streets leading to the ministry as new clashes erupted between security forces and protesters on Mohamed Mahmoud Street. Security forces responded with tear gas, causing suffocation among the protesters. The tear gas smoke caused panic among workers of the central laboratories of the Ministry of Health and students in the area. It should be noted that Tahrir Square witnessed new masses of protesters today, some of which were cleaning the square.
