CAIRO: A curfew from 2am until 6am will be imposed on Cairo's iconic Tahrir Square, Egyptian state television said tonight. The move comes after hours of violent clashes between civilians and the Egyptian army. According to Egypt's Ministry of Health, at least 19 people have been killed in tonight's violence. The number is expected to rise as clashes continue in and around Cairo's downtown area. Tahrir Square was the epicenter of Egypt's January 25 Revolution, which ousted the country's 30-year ruler and his regime from power.
