CAIRO (AP) - Riot police swept in with armored vehicles, bulldozers and helicopters Wednesday to clear two sprawling encampments of supporters of ousted President Mohammed Morsi, sparking running street battles elsewhere in Cairo and other Egyptian cities. At least 149 people were killed nationwide, many of them in the assaults on the protest vigils.
The military-backed interim government declared a monthlong state of emergency, ordering the armed forces to support the police in efforts to restore law and order and protect state facilities. A nighttime curfew for Cairo and 10 provinces also was put into effect.
Clashes also broke out elsewhere in the capital and other provinces, injuring more than 1,400 people nationwide, as Islamist anger spread over the crackdown on the 6-week-old sit-ins of Morsi supporters that divided the counrty. Police stations, government buildings and Coptic Christian churches were attacked or set ablaze.
Smoke clogged the sky above Cairo and fires smoldered on the streets, which were lined with charred poles and tarps after several tents were burned. The smaller camp was cleared relatively quickly, but it took hours for police to take control of the main sit-in site, which is near a mosque that has served as the epicenter of the pro-Morsi campaign.
The assault came after days of warnings by the interim administration that replaced Morsi after he was ousted in a July 3 coup. The two sit-in camps at two major intersections on opposite sides of the Egyptian capital began in late June to show support for Morsi. Protesters - many from Morsi's Muslim Brotherhood - have demanded his reinstatement.
The violence drew condemnation from other predominantly Muslim countries, but also from the U.N. and the United States, which said the crackdown will only make it more difficult for Egypt to move forward.
Vice President Mohamed ElBaradei, a Nobel Peace Prize laureate and pro-reform leader in the interim government, resigned in protest over the crackdown. He wrote that he is not prepared to be held responsible for a "single drop of blood," and that only more violence will result, according to a copy of his letter to interim President Adly Mansour that was emailed to The Associated Press.
The Egyptian Central Bank instructed commercial banks to close branches in areas affected by the chaos, a sign of alarm that the violence could spiral out of control. The landmark Giza Pyramids and the Egyptian Museum also were closed to visitors for the day as a precaution, according to the Ministry of Antiquities.
The turmoil was the latest chapter a bitter standoff between Morsi's supporters and the interim leadership took over the Arab world's most populous country. The military ousted Morsi after millions of Egyptians massed in the streets to call for him to step down, accusing him of giving the Brotherhood undue influence and failing to implement vital reforms or bolster the ailing economy.
The coup provoked similar protests by Morsi's backers after he and other Brotherhood leaders were detained as divisions have deepened, dealing a major blow to hopes of a return to stability after the 2011 revolution that toppled autocratic ruler Hosni Mubarak.
The deposed president has been held at an undisclosed location. Other Brotherhood leaders have been charged with inciting violence or conspiring in the killing of protesters.
"The world cannot sit back and watch while innocent men, women and children are being indiscriminately slaughtered. The world must stand up to the military junta's crime before it is too late," said a statement by the Brotherhood's media office in London emailed to The Associated Press.
The smaller of the two camps was cleared of protesters by late morning, with most of them taking refuge in the nearby Orman botanical gardens on the campus of Cairo University and the zoo.
An AP reporter at the scene said security forces were chasing protesters in the zoo. At one point, a dozen protesters, mostly men with beards wearing traditional Islamist garb, were seen handcuffed and sitting on a sidewalk under guard outside the university campus. The private ONTV network showed firearms and rounds of ammunition allegedly seized from protesters there.
Security forces later stormed the larger camp in the Cairo district of Nasr City and were closing in on the Rabaah al-Adawiya Mosque that has served as the epicenter of pro-Morsi campaign. Several wanted Brotherhood leaders were believed to be hiding in the mosque.
The pro-Morsi Anti-Coup alliance claimed that security forces used live ammunition, but the Interior Ministry, which is in charge of the police, said its forces only used tear gas and that they came under fire from the camp.
The Interior Ministry statement also warned that forces would deal firmly with protesters who were acting "irresponsibly," suggesting that it would respond in kind if its men are fired upon. It said it would guarantee safe passage to all who want to leave the Nasr City site but would arrest those wanted for questioning by prosecutors.
Army troops did not take part in the two operations, but provided security at the locations. Police and army helicopters hovered over both sites as smoke rose over the skyline hours after the police launched the simultaneous actions shortly after 7 a.m. (0500 GMT).
The Health Ministry said 149 people were killed and 1,403 injured across Egypt, but it did not immediately provide a breakdown.
Separately, an alliance of pro-Morsi groups says the 17-year-old daughter of senior Muslim Brotherhood Mohammed el-Beltagy was killed. Asmaa Mohammed el-Beltagy was shot to death in the larger of the two vigils stormed by police. Her brother, Ammar, confirmed her death on his Twitter account.
Two journalists were among the dead - Mick Deane, 61, a cameraman for British broadcaster Sky News, and Habiba Ahmed Abd Elaziz, 26, a reporter for the Gulf News, a state-backed newspaper in the United Arab Emirates, the news organizations reported. Both had been reported to be shot.
A security official said 200 protesters were arrested at both sites. Several detained men could be seen walking with their hands up as they were led away by black-clad policemen.
The Muslim Brotherhood's political arm claimed that more than 500 protesters were killed and some 9,000 wounded in the two camps, but those figures could not be confirmed and nothing in the video from AP or local TV networks suggested such a high death toll.
Mohammed el-Beltagy earlier put the death toll at more than 300 and urged police and army troops to mutiny against their commanders. He also said Egyptians should take to the streets to show their disapproval of Wednesday's raids.
"Oh, Egyptian people, your brothers are in the square. ... Are you going to remain silent until the genocide is completed?" said el-Beltagy, who is wanted by authorities to answer allegations of inciting violence.
Police fired tear gas elsewhere in Cairo to disperse Morsi supporters who wanted to join the Nasr City camp after it came under attack. State TV also reported that a police captain had been abducted by Morsi supporters in the area, but there was no official statement about that.
Islam Tawfiq, a Brotherhood member at the Nasr City sit-in, said the camp's medical center was filled with dead and that the injured included children.
"No one can leave and those who do are either arrested or beaten up," he told AP.
Security officials said train services between northern and southern Egypt have been suspended in a bid to prevent Morsi supporters from traveling from other provinces to Cairo. Clashes erupted on two roads in Cairo's upscale Mohandiseen district when Morsi supporters opened fire on passing cars and pedestrians. Police used tear gas to chase them away.
The security officials spoke on condition of anonymity because they were not authorized to talk to media.
Churches belonging to Egypt's minority Coptic Christians were torched in four provinces south of Cairo - Minya, Assiut, Sohag and the desert oasis Fayoum. In the city of Bani Suef south of Cairo, protesters set three police cars on fire. Farther south in the Islamist stronghold of Assiut, police used tear gas to disperse pro-Morsi crowds in the city center.
Morsi supporters want him reinstated and are boycotting the military-sponsored political process, which includes amending the Islamist-backed constitution adopted last year and holding parliamentary and presidential elections early next year.
White House spokesman Josh Earnest, speaking at Martha's Vineyard, Mass., where President Barack Obama is vacationing, said the crackdown ran counter to the pledges made by Egypt's interim government.
Turkish Prime Minister Recep Tayyip Erdogan's office called the crackdown "a serious blow to the hopes of a return to democracy," and Iran warned that the violence "strengthens the possibility of civil war."
British Prime Minister David Cameron, who also condemned the violence, called for "a genuine transition to a genuine democracy. That means compromise from all sides - the President Morsi supporters but also the military - that's what needs to happen."
U.N. Secretary-General Ban Ki-moon said he regretted that Egyptian authorities chose to use force and urged all Egyptians to focus on reconciliation.
At least 250 people have died in previous clashes since the coup.
Morsi, Egypt's first freely elected president, had just completed a year in office when he was toppled. He has largely been held incommunicado but was visited by the European Union's foreign policy chief Catherine Ashton and an African delegation. Ashton reported that he was well and had access to TV and newspapers.
Several bids by the U.S., the European Union and Gulf Arab states to reconcile the two sides in Egypt in an inclusive political process have failed, with the Brotherhood insisting that Morsi must first be freed along with several of the group's leaders who have been detained in connection with incitement of violence.
The trial of the Brotherhood's leader, Mohammed Badie, and his powerful deputy, Khairat el-Shater, on charges of conspiring to kill protesters is due to start later this month. Badie is on the run, but el-Shater is in detention. Four others are standing trial with them on the same charges.
