Egypt braces for more mass protests; Obama voices concern There were scattered reports Friday of violence, but nothing like the toll from a week earlier. The Anti-Coup Alliance that organized Friday's marches reported one death, saying that a man was killed in the northern city of Tanta as "a result of thugs and the MOI [Ministry of Interior] attacking peaceful protests." The state-run Web site Ahram Gate reported that 25 people were injured in the city in knife fights and rock-throwing involving the Muslim Brotherhood and local families. In the Nile Delta city of Mansoura, residents set fire to a Muslim Brotherhood office, according to the Web site of the Sharouk newspaper. The state-run al-Ahram news site reported that hundreds of residents in the city attacked one of the pro-Morsi marches.. Hundreds of Brotherhood leaders have been arrested in the past week, including the group's leader, Mohammed Badie. The crackdown appears to have crippled the movement's normally robust organizational capacity. One normally well-informed Brotherhood member said Friday he had little information on the day's protests. "Communication is not what it used to be," said the member, who spoke on condition of anonymity for fear of reprisals. "We're not using phones as much," believing them to be tapped, he said. Khaki-colored tanks ringed Tahrir Square in central Cairo, and the government closed the al-Fateh mosque that was the center of clashes the previous Friday, claiming it was under repair. Armored personnel carriers blocked off some roads in Cairo, including the entrances to Mustafa Mahmoud Square, where protesters had hoped to stage a large rally. But at many other protest sites, the security presence was low-key. In Maadi, a sprawling district in southern Cairo, more than 1,000 protesters wound through narrow, dusty streets, waving posters of Morsi, who was detained in the coup and is being held in a secret location. "There is a revolution in the streets of Egypt!" they marchers chanted. Many held up signs showing a hand flashing four fingers - a symbol of outrage at the storming of a pro-Morsi encampment at Rabaa al-Adawiya on Aug. 14. More than 500 people were killed that day in raids by security forces on two major protest sites. Martyrs, martyrs, rest in peace! Wait for us at the gates of heaven!" shouted the demonstrators in Maadi. A few onlookers trained hoses on the crowd to cool them from the scorching midday sun. But most of the bystanders were impassive. There were no signs of police or military as the marchers passed bakeries, pharmacies and food stores, most of them closed for the Muslim holy day. "The tyrants have taken it too far," said one marcher, Nagwa Abdul Azim,45, a businesswoman in a long black robe and yellow headscarf who clutched a red, white and black Egyptian flag. She said she hoped the demonstrations would lead to Morsi's reinstatement - the goal of weeks of demonstrations. But asked whether that seemed likely, she said, "Only God knows." Another demonstrator said protesters were not sure what they could achieve. "There's nothing we can do, just go in the streets, " said the 29-year-old man, who works for a cellphone company. All the people are against us, even the media. He gave his name only as Mohammad, saying he was afraid to be identified. "A lot of my friends, they took them from home and put them in jail," he said. Many Egyptians have supported the crackdown on the Brotherhood. Although Morsi was Egypt's first democratically elected president, he lost popularity because of a withering economy, growing crime and a governing style seen as exclusionary. Private and state media have sought to tie Morsi to the recent violence and even terrorism in recent weeks. Some U.S. lawmakers have called for suspending the annual $1.5 billion in U.S. aid provided to Egypt, most of which goes to the military. But President Obama said in an interview broadcast Friday that such a move might not have much impact. "The aid itself may not reverse what the interim government does," Obama said in an interview with CNN. But I think what most Americans would say is that we have to be very careful about being seen as aiding and abetting actions that we think run contrary to our values and our ideals. Obama reiterated that the U.S. government was examining its relationship with Egypt. "There's no doubt that we can't return to business as usual, given what's happened," he said.
