At least 73 people were killed after a pipeline ruptured by suspected fuel thieves exploded in central Mexico, authorities said on Saturday, as President Andres Manuel Lopez Obrador defended the army despite its failure to clear the site before the blast.

Forensic experts filled body bags with charred human remains in the field where the explosion occurred on Friday evening by the town of Tlahuelilpan in the state of Hidalgo, in one of the deadliest incidents to hit Mexico’s troubled oil infrastructure in years.

One witness described how an almost festive atmosphere among hundreds of local residents filling containers with spilled fuel turned to horror as the blast scattered the crowd in all directions, incinerating clothing and inflicting severe burns.

A number of people at the scene told Reuters that local shortages in gasoline supply since Lopez Obrador launched a drive to stamp out fuel theft had encouraged the rush to the gushing pipeline.

Hidalgo Governor, Omar Fayad, said 73 people were killed and 74 people injured in the explosion, which happened as residents scrambled to get buckets and drums to a gush at the pipeline that authorities said rose up to seven metres high.

Fayad said the condition of many of the injured was deteriorating and that some had burns on much of their body.

Some of the most badly injured minors could be moved for medical attention in Galveston, Texas, he added.
