1 CAIRO - Hundreds of thousands of protesters swelled through villages and cities Sunday, denouncing Egypt's Islamist president and raising fears of a new revolution that could divide the nation, threaten its young democracy and unhinge its already-troubled economy.
2 Protesters against President Mohamed Morsi filled streets and squares, yelling 'Leave, leave' on the first anniversary of his inauguration.
3 The chants echoed against distant cheers of support from Islamists who held rival rallies in what has become a dangerously polarized nation.
4 Scattered violence was reported as fireworks and lasers lighted the Sunday night sky.
5 The state news agency said about 500 young men hurling stones and Molotov cocktails set ablaze the headquarters of Morsi's Muslim Brotherhood party in Cairo.
6 Four people were killed - three of them outside a Brotherhood office in Assiut - in clashes in Upper Egypt.
7 More than 220 were injured nationwide, according to security officials.
8 A youth movement, known as Rebel, has collected more than 22 million signatures on petitions calling for Morsi to step aside for early elections.
9 The president and the Brotherhood have refused to budge and the military has deployed troops around government buildings and along the shipping lanes of the Suez Canal.
10 The breadth of the protests was a stunning rejection of Morsi, and the country's immediate future appeared to hinge on several questions: Can the president survive huge, sustained protests?
11 Will the disparate opposition stay energized?
12 And, if widespread violence ignites, will the military take control of the government as it did immediately after the uprising that overthrew autocrat Hosni Mubarak two years ago?
13 The army has remained inscrutable. Gen. Abdel Fattah al-Sisi, the defense minister, has so far sided with the president and has not signaled a military takeover.
14 The army's rule from 2011 until Morsi's election drew condemnation from human rights groups and blemished its once stellar reputation among most Egyptians.
15 But Sisi has said he will not allow the country to veer into a 'dark tunnel' of political collapse and economic turmoil.
16 In a startling image of how much the public mood has changed over the last year, thousands of protesters, including young mothers and old men, cheered and waved flags at army helicopters flying overhead, a sign that many Egyptians would back a coup.
17 'When the military was in control, things were better.
18 Now we have power cuts, no fuel, and everything's going bad,' said Mohammad Khaled, a 19-year-old electrician who stood in Cairo's Tahrir Square beneath a clear sky.
19 'Morsi promised he would fix many problems in his first 100 days but did nothing.
20 If he's not able to handle it, then he should let someone else do the work.
21 'We succeeded in removing Mubarak, who was here for 30 years; you don't think we can remove Morsi, who has only been here for a year?' Khaled said.
22 'We've been preparing for this day for over two months, and I will stay until he says, ‘I'm stepping down.''.Presidential spokesman Ehab Fahmy told reporters, 'Dialogue is the only way to reach mutual understanding and to reach national agreement around the different issues of our homeland'.
23 Sweeping across boulevards and massing at the presidential palace, raising national flags and flying banners emblazoned with the images of those killed in protests, the protesters sought to rekindle the spirit of the uprising that toppled Mubarak.
24 Morsi's supporters, however, accused their opponents of anarchy for resorting to the streets in a misguided attempt to unseat the country's first freely elected leader.
25 The battle for Egypt lies between these two poles, divided by sectarianism and driven by economic despair.
26 'Egypt is our country, the land of the Nile that carries us all, and it's our duty to protect it without violence or committing assaults,' Coptic Orthodox Pope Tawadros II, whose Christian minority has been increasingly persecuted by Islamists, said on Twitter.
27 'The blood of every Egyptian is precious, please participate, but respect others'.
28 The demonstrations Sunday were largely peaceful, often festive and at times marked by acts of kindness, such as residents pouring water off their balconies in Tahrir Square to cool protesters in the sweltering heat, and by moments of stillness, especially when Islamists prostrated in silence before the mosque.
29 But security officials fear the two sides may collide.
30 At least six people have been killed in recent days.
31 Much of the violence erupted when anti-Morsi forces attacked Muslim Brotherhood offices in Alexandria and other cities.
32 In what has been regarded as a snub to Morsi, the police, who have long been suspicious of Islamists, have refused to protect Brotherhood headquarters.
33 The president's opponents accuse him of betraying the revolution and accumulating power to advance the Brotherhood's Islamist agenda at the expense of a faltering economy, broken institutions and widespread social problems.
34 Morsi supporters accuse remnants of Mubarak's government, including judicial and security officials and prominent businessmen, of instigating unrest to sabotage his government.
35 In an address to the nation last week, Morsi admitted mistakes during his first year in office but spent much of his time vilifying the opposition, outside influences, Mubarak cronies, journalists and others for Egypt's downward spiral.
36 His comments failed to calm a restive poor and working class who have endured months of inflation, power shortages and gas lines.
37 Tourism workers joined marchers in the ancient city of Luxor - home to the Valley of the Kings - to protest a steep slide in visitors.
38 'I live in a room with a hallway, that's all I have,' Khadiga Ibrahim, an illiterate woman in a wheelchair who can't afford knee surgery, said in Tahrir.
39 'I want an apartment. What did Morsi do for us?
40 For the poor? God curse him. I don't want Morsi.
41 I want God's justice. We need someone who is good .
42 someone who cares about us'.

The chants echoed against distant cheers of support from Islamists who held rival rallies in what has become a dangerously polarized nation .
