Authorities in Egypt say two people have been killed in clashes between Islamist protesters and their opponents on the final day of campaigning before next week's presidential election. The Health Ministry says one person was killed in Cairo and another in an oasis town southwest of the capital. At least 23 people were hurt. Also today, security officials say a police officer has died from wounds sustained in a firefight with militants in the restive Sinai Peninsula. He was shot in the neck when his patrol came under attack near the border with Gaza yesterday. Egyptians will vote on Monday and Tuesday for their new president. The former army chief who led last year's ouster of Islamist President Mohammed Morsi is expected to win.
