Hundreds are still battering the police forces near Qasr El-Nil Bridge in downtown Cairo.
Clashes continued in the Nile Corniche area near Semiramis hotel as protesters continue to approach the security forces while the latter respond with firing tear gas canisters which the protesters throw into the Nile.
These clashes continued throughout Sunday night from three different points around Tahrir Square, after President Mohamed Morsi's speech at around 10 p.m.
Dozens of protesters hurled rocks and Molotov cocktails at police near the Qasr El-Nile entrance to Tahrir Square. Police responded with dense volleys of tear gas in an attempt to push protesters back into the square.
Clouds of smoke could still be seen around Tahrir on Monday morning and tear gas leaked into the nearby Sadat metro station, causing a brief suspension of services.
On a similar note, the stage built in Tahrir has threatened protesters would storm into Sadat metro station in Tahrir, Cairo Security Directorate and also destroy the stone wall erected by the army in Sheikh Rihan Street, MENA reported.
The protesters said they would escalate actions in response to "violence security forces are using with the protesters."
Metro rails were blocked by protesters for limited periods of time over the past few days as a means to put pressure on Egyptian authorities.
Some protesters also blocked main routes in Cairo like the 15 May and 6 October Bridges.
