The plane, carrying Algerian President Abdel Aziz Bouteflika, landed Sunday at Bufariq military airport west of the capital, coming from Geneva, amid heavy security in the presidential palace area of Zeralda.
The Algerian president, who faces mass protests in Algeria, has been treated in a hospital in the Swiss city of Geneva over the past two weeks.
Bouteflika left the country on Feb. 24 for treatment.
Bouteflika, 82 years old, has rarely appeared in public since he suffered a stroke in 2013 and his decision to run in the presidential election has sparked major protests in Algeria over the past three weeks.
Many public figures, including members of the ruling National Liberation Front, and lawmakers resigned to join protests against a political system dominated by veterans in Algeria's war of independence from France.
Algerians, angered by job shortages, unemployment, corruption and elite elders, have not shown a desire to back down despite Bouteflika's bid for early presidential elections a year later if he wins the presidential race next month.
