CAIRO: Egypt's Islamist groups have decided to boycott a march planned for tomorrow against the Emergency Law. Seventeen political movements and parties have announced their participation in tomorrow's march, which will last from 4-6pm. There will be no sit-in. The Islamic groups, however, will not participate in the march. Islamists say continual protests and marches negatively affect Egypt's economy. Those participating in the march announced their complete refusal of the decision to reactivate Egypt's Emergency Law, which was announced by the country's ruling military council last week. Egyptians have lived under Emergency Law for more than 30 years, and repealing it was one of the main demands of the country's January 25 Revolution. Among other things, the Emergency Law allows search and seizure without a warrant and prohibits groups of more than five from gathering without a permit. Saad Katatni, head of the Muslim Brotherhood-affiliated Freedom and Justice Party, said the Islamic powers are not participating in the march because they were not officially invited. Katatni warned that any protest can turn against the country's interests and harm the economy. He said the Brotherhood is totally against the Emergency Law but rejected the mechanism of a march. He said the country's interest must be the priority.
