Two suicide bombings in Egypt’s South Sinai killed a soldier and wounded at least seven people yesterday, fewer than four weeks before a presidential election is due to be held, official sources said.

In other violence, a policeman was killed in a Cairo bomb attack while, in the port city of Alexandria, two people were shot dead when deposed President Mohamed Morsi supporters clashed with residents.

Militant attacks and other political violence have spiralled since the army overthrew Morsi, a Muslim Brotherhood leader, in July after mass protests against his rule.

Former army chief Abdel Fattah al-Sisi, who led the action, is expected to win the presidential election on May 26 and 27.

The suicide attack in El-Tur, a town on the main road between Cairo and the tourist resort of Sharm El-Sheikh, killed a soldier as well as the bomber. Three policemen and another soldier were wounded, an Interior Ministry statement said.

Four Egyptians were wounded in the second attack, further south on the road between El-Tur and Sharm El-Sheikh, the Interior Ministry and security sources said.

Last month the Egyptian military said it had gained complete control of the Sinai Peninsula.
