Egyptian President Mohamed Morsi said late Sunday that he won't stand by in the wake of recent violence, imposing a 30-day curfew in Port Said, Ismailia and Suez. "I will act, and now I am acting," President Morsi said in a nationally televised speech. Under his order, people in those governorates cannot go out between 9 p.m. to 6 a.m. The three northeastern Egyptian cities, all of them along the Suez Canal, have been sites of deadly violence in recent days, according to a report of CNN. In his Sunday night speech, President Morsi said people in these and other places had attacked public and private institutions, "terrorized civilians," blocked roads and taken up arms. Those responsible will face "justice as soon as possible," the president said. He added he has instructed the Interior Ministry, which oversees security forces, "to deal properly, and also with force, against those who attack the nation's institutions." The President insisted Egyptian authorities are capable of restoring peace and security. said "dialogue is the only way to bring about stability and security." To this end, he invited representatives from 11 political parties to a meeting Monday. His spokesman, Yasir Ali, told state-run Nile TV that this meeting "is meant to address problems in Egypt, as opposed to express anger." It's a sentiment that Morsi himself expressed a short time earlier, saying dialogue amongst various Egyptians was the only way for the country to reach peace and prosperity. "We are going that way, all together," he said. "God bless Egypt, and make her safe for her people and the whole world."
