Dramatic video: Egyptian police van plunges off bridge as Islamists call for 'Friday of anger' Vision his emerged showing the armoured police van ramming protesters before reversing and driving off the bridge during the violent scenes in Egypt. Courtesy TeenisHaven ISLAMISTS in Egypt called for a "Friday of anger" in Cairo after a crackdown on protesters that killed nearly 600 people nationwide. "Anti-coup rallies tomorrow will depart from all mosques of Cairo and head towards Ramsis square after (traditional Friday) prayer in 'Friday of Anger'," Muslim Brotherhood spokesman Gehad al-Haddad wrote on his Twitter account. The call raised fears of fresh violence after the death toll from nationwide clashes following Wednesday's operation to clear two camps of supporters of ousted president Mohamed Morsi rose to 578, making it Egypt's bloodiest day in decades. It came as dramatic new video showed how an armoured police van rammed protesters and then plunged off a bridge during the violent crackdown in the capital.

The scenes happened during the deadly crackdown by Egypt's interim government on supporters of ousted president Mohamed Morsi which sparked clashes that killed hundreds and drew international censure. The death toll has soared to as turmoil spreads across the country, although the Muslim Brotherhood estimates the carnage at up to four times the number.

Reports said up to five officers were in the vehicle when it tumbled off the bridge. As Egyptian Islamists went on the counterattack, the UN Security Council called on both the Egyptian government and the Muslim Brotherhood to exercise "maximum restraint" and end violence spreading across the country.

Islamists attacked police facilities in the Sinai and the central city of Assiut, killing two policemen, and also torched the headquarters of the provincial government in Giza, near the capital. In Alexandria, hundreds of Morsi supporters cut the road on the corniche, chanting for their deposed president, state media reported.

The Health Ministry says 288 of those killed were in the largest protest camp in Cairo's Nasr City district, while 90 others were slain in a smaller encampment at al-Nahda Square, near Cairo University. Egypt has authorised police to use deadly force to protect police and key institutions from attacks. Egyptian men work to organise the bodies of supporters of deposed Egyptian President Mohammed Morsi, killed during a violent crackdown by Egyptian Security Forces. Egypt's interior ministry has instructed police to use live ammunition in dealing with attacks on government buildings and police forces. "The interior ministry has instructed all forces to use live ammunition to counter any attacks on government buildings or forces," a statement said, after Islamists killed two policemen and torched a provincial government headquarters in Cairo. The Muslim Brotherhood, from which Mr Morsi hails, said a march was planned later on Thursday from the Al-Iman mosque in the capital "to protest the death of their relatives." Egyptian state television shows Egypt's interim prime minister Hazem al-Beblawi addressing the nation in Cairo after the violent clashes erupted. Inside the building, the names of the dead were scribbled on the white sheets covering the bodies, some of which were charred, and a list with 265 names was plastered on the wall. Heat made the stench from the corpses almost unbearable inside the mosque, where posters of Morsi were piled up on in a corner. Many people complained that authorities were preventing them from obtaining permits to bury their dead, although the Muslim Brotherhood announced that several funerals had been held for identified victims on Thursday. Fathallah denied that permits were being withheld. Spokesman Gehad al-Haddad said demonstrations would continue. Egyptians walk among the burned remains of the Rabaah al-Adawiya mosque, in the center of the largest protest camp of supporters of ousted President Mohammed Morsi. We will always be non-violent and peaceful. We remain strong, defiant and resolved," he tweeted. We will push forward until we bring down this military coup. Morsi loyalists have insisted their demonstrations are exclusively peaceful, but an AFP reporter saw several protesters carrying weapons at Rabaa al-Adawiya, one of the camps, on Wednesday. A mass funeral was held in Cairo for some of the 43 security troops who authorities said were killed in Wednesday's clashes. Interior Minister Mohammed Ibrahim, who is in charge of the police, led the mourners.

A police band played solemn music as red fire engines bore the coffins draped in white, red and black Egyptian flags in a funeral procession. In Cairo, trucks cleared debris from the charred sites there and at the Nahda Square protest camp, both occupied for weeks by Morsi loyalists after he was ousted by the military on July 3. As the death toll from the carnage soared, condemnation of the assaults poured in, with France warning of the threat of "civil war" and Turkey demanding UN action. The United Nations Security Council launched emergency consultations on the crisis at the request of France, Britain and Australia. After the meeting, they called for "maximum restraint." The United States led the global outcry against the "deplorable" violence, while Paris, London, Berlin and Rome summoned Egypt's ambassadors to voice their strong concern.

US President Barack Obama said on Thursday the United States has cancelled military exercises with Egypt to protest the killing of hundreds of protesters. Mr Obama warned that Egypt had entered a "more dangerous path" but stopped short of suspending annual military aid. "While we want to sustain our relationship with Egypt, our traditional cooperation cannot continue as usual when civilians are being killed in the streets and rights are being rolled back," Mr Obama said. The presidency in Egypt responded with: "Egypt is facing terrorist acts targetting government buildings and vital installations ... The presidency, while regretting the loss of Egyptian lives, is working strongly to bring about social peace and security. The statement was released by interim President Adly Mansour's office. The presidency said it also feared that Obama's remarks would "encourage" armed groups "in their opposition to stability and democratic transformation." "Egypt values the sincere positions of world states, but fully affirms its complete sovereignty and self-determination," the presidency added. French President Francois Hollande said "everything must be done to avoid a civil war," adding that France "is committed to finding a political solution and calls for elections to be held as soon as possible, in line with the commitments made by Egypt's transitional authorities." Turkey's Prime Minister Recep Tayyip Erdogan, a Morsi supporter, had earlier called for an urgent UN Security Council meeting over Egypt's "massacre." Turkey later Thursday recalled its ambassador to Cairo "to discuss the latest developments." UN rights chief Navi Pillay called for "an independent, impartial, effective and credible investigation of the conduct of the security forces." "The number of people killed or injured, even according to the government's figures, point to an excessive, even extreme use of force against demonstrators," she said. Only the United Arab Emirates and Bahrain voiced support for Egypt's military leaders, saying it was the state's duty to restore order. Egypt's now-censored press trumpeted the end of the pro-Morsi demonstrations. The newspapers carried photos of protesters brandishing weapons and throwing stones, but none from makeshift morgues where dead protesters were lined up in rooms slick with blood. Numerous churches were attacked as police broke up the protests, with Christian activists accusing Morsi loyalists of waging "a war of retaliation against Copts in Egypt." Wednesday's violence was Egypt's worst in decades, exceeding even that seen during the 18-day uprising that ousted president Hosni Mubarak in 2011. While the health ministry put the toll at 525, the Brotherhood spoke of 2200 dead overall and more than 10,000 wounded. The killing prompted interim vice president and Nobel laureate Mohamed ElBaradei to resign, saying he was troubled over the loss of life, "particularly as I believe it could have been avoided." Despite the condemnation from abroad, Egyptian interim prime minister Hazem al-Beblawi praised the police for their "self-restraint" and said the government remained committed to an army-drafted roadmap calling for elections in 2014. Mr Beblawi justified the use of force saying Morsi loyalists had been sowing chaos around the country, "terrorising citizens, attacking public and private property." "The state had to intervene to restore security and peace for Egyptians," Mr Beblawi said, adding that a state of emergency declared by the president was necessary under the circumstances. He urged all sides to work for the next phase in preparation for fresh elections in 2014. This government is committed to the roadmap, to having a consensus constitution that protects all rights... based on social justice. Wednesday's violence was a dramatic turn of events for the Brotherhood, which just over a year ago celebrated Mr Morsi's victory as Egypt's first elected president. His single year in power, marred by political turmoil, deadly clashes and a crippling economic crisis, turned many against the Islamist movement, with millions taking to the streets on June 30 to call for his removal.
