President Abdelaziz Bouteflika returns to Algeria amid mass protests
The 82-year-old leader spent two weeks in a hospital in Geneva. Since having a stroke in 2013 he has rarely been seen in public.
The president's plane flew to the Swiss city on Sunday before returning to Boufarik military airport, reports say.
Mr Bouteflika's announcement that he would stand for re-election next month sparked huge protests across Algeria.
The demonstrations, which have seen tens of thousands of people take part, are thought to represent the biggest threat so far to Mr Bouteflika's 20-year rule.
