Algeria is experiencing an intense summer heatwave with firefighters also battling several wildfires across the north of the country.
News of the orphanage fire has shocked and outraged many.
“May God have mercy on them,” the civil defence unit said, external as it announced the death toll on Thursday, several hours after the blaze began.
President Tebboune said in a statement: “It is with a heart resigned to the will of God that I learned of the death of children and the injury of others.”
The authorities said five children with reduced mobility had been safely rescued from the blaze.
The fire has prompted opposition figures, critical media and social media users to demand answers over possible negligence.
The opposition Jil Jadid party called for a transparent investigation into the incident and legal accountability for any negligence or safety failures.
It also demanded a nationwide review of fire safety standards at orphanages, care homes, hospitals and schools.
Journalist Akram Kharief described the fire as a “national tragedy”, called for fire safety audits at all public institutions and questioned why Algerians could not live “a normal life in a normal country”.
Comments on the social media pages of several news outlets wanted to know who had been supervising the children overnight, while some called for resignations.
Meanwhile, Le Matin d’Algérie – a website critical of the government – noted the absence of the mayor and provincial governor during the initial rescue operation.
Pro-government news site Algerie Patriotique said the country should establish the truth “without complacency” and determine whether the deaths could have been prevented.
