An Algerian court Thursday sentenced 49 people to death over the lynching of a man falsely accused of starting deadly forest fires during an extended heatwave last year, state media reported.
The North African country has, however, maintained a moratorium on carrying out death sentences since the last executions in 1993.
Onlookers had beaten 38-year-old Djamel Ben Ismail to death after he turned himself in at a police station in the Tizi Ouzou region.
He had gone there upon hearing that he was suspected of arson, at the height of blazes which killed at least 90 people nationwide.
It later emerged that Ben Ismail, an artist from Miliana (230 kilometres or 140 miles further west), had headed to the region as a volunteer to help put out the fires.
Algeria, Africa's biggest country, was one of several Mediterranean nations to face devastating wildfires last year.
The court in Dar El Beida on Thursday "sentenced 49 people to execution over (Ben Ismail's) murder and mutilation of his body," the APS news agency reported.
The court also handed 28 other defendants jail terms of two years to a decade without parole, APS said.
Videos posted online at the time showed a crowd surrounding a police van and beating a man inside it, then dragging him out and setting him on fire, with some taking selfies.
The shocking images were widely shared and sparked outrage in Algeria.
Algeria's LADDH human rights group called for calm and for those responsible for the "despicable murder" to be brought to justice.
"These images constitute yet another trauma for the family and for the Algerian people, already shocked" by the fires, it said.
The victim's father, Noureddine Ben Ismail, was widely praised for calling for calm and "brotherhood" among Algerians despite his son's murder.
The fires were spurred by a blistering heatwave, but authorities also blamed arsonists and "criminals" for the outbreaks.
The Movement for the Autonomy of Kabylie (MAK), which Algiers classifies as a "terrorist organisation", rejected the accusations.
Authorities also blamed the independence movement of the Berber-majority region of Kabylie that extends along the Mediterranean coast east of Algiers.
Although much of Algeria's interior is desert, the north has more four million hectares (10 million acres) of forest, which is hit every summer by fires.
Critics say the authorities failed to prepare for the blazes.
Algeria's army mobilised five helicopters, while its emergency services used three water-bombing helicopters to fight the flames, with firefighting aircraft also coming to help from Europe.
Climate scientists have repeatedly warned that man-made global warming will bring higher temperatures and more extreme weather events across the world.
