MEXICO CITY — Mexican Federal crime investigators began their probe Monday of what caused a massive oil pipeline explosion that killed 28 people and laid waste to parts of a central Mexican city.
Valentin Meneses, interior secretary for the state of Puebla, where San Martin Texmelucan is located, said 32 homes were completely destroyed and 83 partially damaged by the blast."A commission has been named that together with Pemex (Petroleos Mexicanos, the state oil company) is investigating what happened," Meneses said.
The scene of the disaster has been closed off and is being patrolled by police, Meneses added. Cleanup experts are also making sure there is no combustible material remaining in drains, which could threaten a new explosion.
