Algiers - Hundreds of police officers and soldiers were deployed in the Algerian capital Algiers on Sunday, as ailing President Abdelaziz Bouteflika was set to defy mass street protests by officially registering his candidacy for a fifth term in office.
Security personnel were stationed at focal points for protesters and around state institutions in the city, witnesses said.
Security vehicles meanwhile patrolled Algiers' main roads, they added.
Bouteflika is widely expected to submit his candidacy papers later Sunday, the last day for registration to run in next month's presidential election.
Mass protests have erupted across Algeria since Bouteflika announced last month his intention to seek a new five-year term in the April 18 poll.
