Military and security sources said that the army had seized a fuel storage tank hidden by black marketeers and was in the midst of handing out gasoline to residents when the explosion took place.
Lebanon is suffering from a severe fuel shortage, leading to long lines at gas stations and extended blackouts. The disaster happened in the town of Altalil, in the Akkar region that is one of Lebanon’s poorest areas.
About 200 people were nearby at the time of the explosion, eyewitnesses said.
Caretaker Health Minister Hamad Hassan said the worst cases of burns probably needed quick treatment abroad to save their lives.
“We need urgent help to evacuate some of the injured abroad..there are cases (of burns) that are more than the ability of Lebanese hospitals to handle,” he said.
Army and security forces personnel were among the casualties, sources said.
Accounts varied as to what caused the explosion.
“There was a rush of people, and arguments between some of them that led to gunfire which hit the tank of gasoline and so it exploded,” said a security source.
The Red Cross said its teams were still searching the explosion site.
The majority of the injured are in serious condition, said Dr. Salah Ishaq of al-Salam Hospital. “We can’t accommodate them, we don’t have the capabilities. It’s a very bad situation.”
With Lebanon deep in economic crisis, hospitals have warned that fuel shortages may force them to shut down in the coming days, and have also reported low supplies of medicines and other essentials.
“The Akkar massacre is no different from the port massacre,” said former Prime Minister Saad al-Hariri on Twitter, referring to last year’s massive explosion at the port in Beirut. He called on Lebanese officials including the president to take responsibility and resign.
Hariri is the leading Sunni Muslim politician, the dominant religion in Lebanon’s north, and has been in open opposition to Lebanese President Michel Aoun.
Aoun expressed condolences, writing on Twitter that “this tragedy that befell our dear Akkar has made the hearts of all Lebanese bleed”. He added that he asked the judiciary to investigate the circumstances that led to the explosion.
