Splits in Egypt Leadership Amid New Protests Feuding erupted within Egypt's new leadership on Sunday as secular and liberal factions wrangled with ultraconservative Islamists who rejected their choice for prime minister, stalling the formation of a new government after the military's ouster of President Mohammed Morsi. At the same time, the shows of strength over the removal of Egypt's first freely elected president were far from ending, with tens of thousands in the streets Sunday from each side. The military deployed troops at key locations in Cairo and other cities amid fears of renewed violence. The Muslim Brotherhood pushed ahead with its campaign of protests aimed at forcing Morsi's reinstatement, bringing out large crowds in new rallies. Its officials vowed the group would not be "terrorized" by arrests of their leaders and the shutdown of their media outlets. The Brotherhood's opponents, in turn, called out large rallies in Tahrir Square and other squares in Cairo and several cities to defend against an Islamist counter-push. Military warplanes swooped over the crowd filling Tahrir, drawing a heart shape and an Egyptian flag in the sky with colored smoke. Two days ago, clashes between the rival camps left at least 36 dead and more than 1,000 injured nationwide. Senior Brotherhood members Saad Emara said there was no possibility for any negotiations with the new leadership after "all betrayed us," and following the military's clampdown on the group. "We are not regressing to a Mubarak era but to ... a totalitarian regime," he told The Associated Press. Anything other than protest is suicide. Morsi and five top Brotherhood figures are currently in detention, and around 200 others have arrest warrants out against them. The group's TV station and three other pro-Morsi Islamist stations were put off the air. Among those detained is Badie's deputy Khairat el-Shater, seen as the most powerful figure in the group and its main decision-maker. The wrestling over the prime minister spot underlined the divisions with the collection of factions that backed the military when it pushed Morsi out of office on Wednesday and installed a senior judge, Adly Mansour, as an interim president. At center stage of the feuding is the ultraconservative Salafi al-Nour Party, the sole main Islamist faction that sided with the mainly secular groups that led the charge against Morsi. On Saturday, the party blocked the appointment of reform leader Mohammed ElBaradei, a favorite of liberal, leftist and secular groups, as prime minister. Another member of the coalition, Tamarod, the main organization behind the massive protests last week calling for Morsi ouster, said ElBaradei was still its candidate for the post. It railed against al-Nour on Sunday, accusing it of "blackmail" and "arm-twisting." Showing the outside pressures on al-Nour, Emara of the Brotherhood said al-Nour "has lost credibility and trust after they sided with the takeover" - a sign the Brotherhood hopes to draw the party's Salafi supporters behind it in the streets alongside other Islamists. The prime minister is to be the real power in whatever interim government emerges, since the president's post will be largely symbolic. The prime minister will also likely have strong influence on the process of writing a new constitution. That's a major concern of al-Nour, which pushed hard for the Islamic character of the charter pushed through under Morsi's administration, which was suspended after his ouster.
