Algeria's president informed the country's constitutional council Tuesday of his decision to stand down, state news agency APS has reported.

Abdelaziz Bouteflika's resignation followed an aggressive call from the country's defense ministry for the embattled president to quit "immediately" following weeks of street protests.

How we got here:

• The defense ministry's call came hours after the vice defense minister, General Ahmed Gaid Salah, said: "We will support the people until their demands are fully and completely satisfied."
• On Monday, the president's office announced that the 82-year-old would step down before his mandate expired on April 28.
• A new caretaker government headed by recently appointed Prime Minister Noureddine Bedoui was announced on Sunday.
• While he had declared his candidacy for a fifth term in February, he then withdrew and postponed the election in response to massive protests against his rule.

'For the Algerian people to decide'

After Bouteflika's announcement, several hundred people gathered in downtown Algiers on Tuesday night, singing songs and waving Algerian flags.

French Foreign Minister Jean-Yves Le Drian hailed the move as "an important page in the history of Algeria that turns." 

"We are confident in the ability of all Algerians to continue this democratic transition in the same spirit of calm and responsibility," Le Drian said in a statement.

The United States said the future of Algeria is up to its people, following Tuesday's announcement.

"Questions about how to navigate this transition in Algeria, that is for the Algerian people to decide," a state department official told reporters. 

Ailing leader: Bouteflika ruled Algeria for 20 years. He had a stroke in 2013 and has rarely been seen in public since. He came to power with the support of an army battling Islamist guerrillas, but nobody expected him to stay in office for so long.

Protests since February: Bouteflika's decision to seek a fifth term despite rarely being seen in public since his stroke sparked six weeks of protests throughout the country. The demonstrations caused some of Bouteflika's faithful backers to gradually desert him, including Salah, who had pressured the Algerian leader to step down.

What happens next: The Constitutional Council is expected to meet on Wednesday to confirm Bouteflika's resignation. Under the constitution, the speaker of the upper house, in this case Abdelkader Bensalah, a Bouteflika ally, steps in as the interim president for a maximum of 90 days so that elections can be organized.
