Algeria’s ailing President, Abdelaziz Bouteflika has returned to the country after two weeks in a Swiss hospital.

A plane carrying the 82-year-old leader landed at Boufarik military airport near the capital, Algiers, as protests against his 20-year rule continue.

Teachers and students have gone on strike at several universities, with thousands joining demonstrations.

They are against the president’s plan to seek a fifth term in office.

Bouteflika said the mass demonstrations, which broke out last month and represent the biggest threat so far to his rule, could plunge the country into “chaos”.
