Algerian officials say the All Africa Games are continuing as planned in Algiers despite a suicide bomb attack near the capital on Wednesday.
Officials say security would be stepped up around the competition sites.
Before the opening ceremony Wednesday, a suicide bomber killed at least eight soldiers and wounded 35 others in Lakhdaria, a village east of the capital, Algiers.
The al-Qaida Organization in the Islamic Maghreb, formerly known as the Salafist Group for Preaching and Combat has claimed responsibility for the bombing.
The group also claimed responsibility for a number of attacks that have rocked the region, including two car bombings in April that killed 33 people.
The All Africa Games are a regional multi-sport event held every four years. Competing athletes must be from the African continent.
The competition is set to last until July 23.
