Clashes in Tahrir Square between protesters and Central Security Forces (CSF) are taken to the next level as gunfire is heard and tear gas canisters are thrown to disperse the enraged crowd Clashes in Tahrir Square between protesters and Central Security Forces (CSF) are taken to the next level as police forces throw tear gas to disperse the enraged crowd. Gunfire has been resounding in the epicentre of the revolution, as well. The protesters, who have increased to around 500, replied to the attacks by hurling stones and other projectiles onto the CSF. Earlier this morning, Central Security Forces forcibly dispersed the few demonstrators who remained in Tahrir Square following yesterday's Friday of One Demand mass protest. Riot police dismantled the few tents left over from yesterday and have reportedly arrested several activists in the process to completely evacuate the square. Several people were reportedly injured and arrested in the process. After the police attacks, the protesters – who were joined by others – returned to the central island as the CSF withdrew from Tahrir. Later, demonstrators pelted six CSF blue vans with stones as they left the Ministry of Interior's headquarters, crossing through Tahrir, who are still adamant to occupy the central island. Soon after, one of the protesters managed to hijack a van (it cannot be confirmed if it was one of the six vans) and drove it back to his comrades, who all took out their frustration on the huge vehicle. The police eventually resorted to tear gas in an attempt to evacuate Tahrir Square. Most of the political forces that took part in Friday's demonstration opted not to stage a sit-in at Tahrir, leaving defenceless a handful of protesters – who decided otherwise – against police in the epicentre of the January 25 Revolution. The ongoing tensions in Tahrir could well cause the already-tarnished relationship between the police and citizens to take a turn for the worse. The clashes closed off traffic through the central Tahrir Square, causing mass traffic jams elsewhere in Cairo.
