CAIRO (AFP) - Egyptian activists called on Saturday for a million-person march on the eve of landmark polls as Egypt's military leader reached out to key opposition figures amid a deepening political rift. The Revolution Youth Coalition, formed during the uprising that drove Hosni Mubarak from power in February, called on its Facebook page for mass protests in Tahrir Square and across Egypt on Sunday to demand the end of military rule. Earlier, a 19-year-old demonstrator was killed after a protest outside the cabinet headquarters against military leader Field Marshal Hussein Tantawi's appointment on Friday of Kamal al-Ganzuri as the country's new prime minister. Among the demands of the activist alliance is the replacement of Ganzuri and the cabinet he has been tasked with forming by a national salvation government and the immediate trial of all those involved in killing demonstrators. Egypt on Saturday deported three American students arrested during protests in Cairo's Tahrir Square to demand an end to military rule, an airport official told AFP. The three students of the American University in Cairo were ordered released on Thursday after three days in custody. According to the official MENA news agency, the trio had been arrested with a bag allegedly containing a water bottle filled with petrol - as clashes raged around Tahrir between police and protesters. At least 42 people have now died in a week of clashes between protesters and police that erupted on November 19 and which have also left more than 3,000 injured. Tantawi held separate talks on Saturday with presidential hopefuls Mohamed ElBaradei, former head of the UN nuclear watchdog, and ex-Arab League chief Amr Mussa, state media reported, as protesters demanding an end to military rule remained camped out in Tahrir Square. A political source told AFP that the meetings discussed the formation of an advisory panel to the military council. ElBaradei's office said no agreement had been discussed during the meeting on "the next phase" of the revolution, but added that he was "continuing negotiations to achieve the demands of the revolutionaries." He and Mussa were among those proposed by protesters as members of a national salvation government. Meanwhile, the European Union's foreign policy chief Catherine Ashton Saturday called for an end to the violence in Egypt between demonstrators and security forces just two days from elections. "Violence must stop and the rule of law has to be maintained," Ashton said in a statement about the clashes that have left more than 40 dead. Protesters have taken to Cairo's Tahrir Square for an eighth day Saturday demanding the immediate end of military rule and transfer to a transitional civilian govt. "All political parties should reaffirm their commitment to the democratic process that Egypt has embarked upon," Ashton said. "The swift shift of power to civilian rule is a key element of the transition and should happen as soon as possible on the basis of an inclusive dialogue," she added, noting the commitments made by the SCAF.
