Five people were killed Friday in violence in Egypt, just hours before the start of campaigning for the country's upcoming presidential election.
Egyptian officials say two suicide attacks in Egypt's South Sinai province, one on a security checkpoint and the other on a passenger bus, killed a soldier and a civilian. Eight people were wounded in those attacks near the South Sinai capital of Tor.
Another attack near a courthouse in Cairo left a policeman dead. A top security official said "terrorists" were behind that incident.
In the Mediterranean port city of Alexandria, two people died in clashes between supporters of ousted Islamist President Mohamed Morsi and local residents.
There is tension in Egypt with voters due to go to the polls on May 26 and 27 to elect a new president. Egypt has been bitterly divided over Mr. Morsi's ouster.
Powerful former military chief Abdel-Fattah el-Sissi, who led the overthrow of Mr. Morsi last July, is widely expected to win the election.
