The death toll from an explosion at a bakery in Paris has risen to four, according to authorities.
The blast occurred on Saturday morning in the Rue de Trevise in the 9th arrondissement of north-central Paris.
Dozens of people were injured with 10 of them still in a critical condition.
Yesterday, three people were confirmed dead, two firefighters and a Spanish national, however the death toll has since risen.
Firefighters found a body among the rubble.
Paris fire department spokesman Eric Moulin told reporters about 30 firefighters were at the site to search for other potential victims, amid a mountain of debris and wrecked cars.
Paris authorities said 12 neighbouring buildings that were damaged by the blast apparently due to a gas leak have been evacuated.
Temporary accommodations were provided for about 40 residents while dozens of others have been housed by family and friends.
Firefighters pulled injured victims out of windows and evacuated residents as smoke billowed out of the building after the incident at 9am local time (8am GMT).
Paris prosecutor Remy Heitz said that the cause appears to be an accidental gas leak.
He said that Paris firefighters were already at the scene to investigate a suspected gas leak at the bakery when the explosion happened.
An investigation was opened to determine the exact cause of the blast, he said.
Witnesses described the overwhelming sound of the blast and people trapped inside nearby buildings.
Charred debris and broken glass covered the pavement around the apartment building housing the bakery, which resembled a blackened carcass.
