Cairo , Egypt ( CNN ) -- A record crowd in Cairo 's Tahrir Square swelled Tuesday afternoon , a sea of Egyptians from every walk of life in a demonstration dubbed the `` march of millions . '' Tens of thousands prayed on their knees on the asphalt in unison under the sprawling city 's winter sun , and then chanted `` leave , leave '' in a deafening roar to their president , Hosni Mubarak . As the throngs congregated , Egypt 's Nile TV showed live pictures of car traffic crossing a bridge over the Nile River , with bulletins announcing that a curfew would be imposed again on Tuesday starting at 3 p.m . Soldiers and plain-clothed security officers searched demonstrators and controlled access to Tahrir , or Liberation Square , which has been the focal point of protests against Egypt 's embattled Mubarak , 82 . After the first lines of security , scores of self-appointed volunteers from the protest movement conducted their own searches of bags , and ordered arriving people to show their identity cards as they streamed in . One man handed out leaflets , urging demonstrators to behave in front of foreign journalists covering the event . `` As you know all media organizations are here to follow your efforts , '' the leaflet read , `` In order to show Egypt in a positive light , we insist that you follow a peaceful approach in expressing your requests and ideas . '' Men and women continued a practice that has sprung up here over the last week ... standing alone in the street , holding up hand-made signs , and posing proudly for the cell phone photos of passers-by . `` Mubarak has been here since Ronald Reagan , '' shouted one man , who held up a sign that said `` Get Out Mubarak '' in English . Said El Sisi , 23 , said he and his father and brother traveled two hours on five different buses from their village outside Cairo to attend the demonstration . `` I 'd like to see change in my country , '' El Sisi said , as he walked slowly with hordes of people through security checkpoints towards the square . `` I 'd like to see a president in Egypt every eight years like in other countries . ... this is just the country of rich people . I graduated from university and I speak four languages but I ca n't find a job because of nepotism and corruption . To do anything you have to pay money . '' Many Egyptian opposition parties have embraced today 's demonstration , which was promoted through fliers and leaflets , since the government has shut down almost all of the internet connections in the country . `` Today we are all together in Tahrir Square , '' said George Issac , a member of the opposition group Kefaya , which means `` Enough '' in English . `` This revolution is a revolution of the young generation . We are just supporters , '' Issac said . He claimed Egypt 's long repressed opposition parties were working together with one goal , to remove President Hosni Mubarak . In another part of Cairo , an aide to Ayman Nour said the former opposition candidate for president was holding talks with officials from the liberal secular opposition Al Wafd party . `` You can not call us Kefaya or Muslim Brotherhood or leftists or anything , '' Issac explained . `` We talk today as Egyptians . '' But Issac also said his party opposed the announced goal of some demonstrators , who planned to march from Tahrir Square to the Presidential Palace . `` I send a message for all the demonstrators . Do n't leave the square , '' Issac said , in a telephone interview with CNN . A march of tens of thousands of people , if not more , would put the protesters in tense confrontations with the Egyptian troops who have established checkpoints throughout the city . At the outskirts of Tahrir Square , army officers drove a truck blaring patriotic music from loudspeakers . On Monday , the military announced it would not use force against the demonstrators . `` The presence of the armed forces in the Egyptian streets is for your benefit to protect your safety and peace , '' an unnamed military spokesman announced on state television Monday night . `` Your armed forces will not use violence against this great people , who have always played a significant role in every moment of Egypt 's great history . '' And deeper in the throngs of jubilant protesters , one of the men who searched arriving participants wore a camouflage military uniform underneath civilian pants and jacket in an apparent effort to blend in with the crowd .
Crowds chant for people to leave . Tahrir Square is the focal point of protest . Opposition parties join the demonstration .
