An early evening explosion at the headquarters of Mexican state oil company Pemex has killed 25 people and injured more than 100. The explosion happened just after 4pm local time at the Pemex Office Complex in Mexico City, taking out two floors of an administrative building next to the Pemex tower.
The scene on the ground is reportedly chaos. Crews, including military troops, have been digging through rubble searching for survivors. More than 100 people were injured in the blast and ensuing evacuation, and the death toll is expected to go up. It is uncertain how many are missing.
Right now, it is unknown what caused the explosion. Early reports blamed it on an electrical failure, and even an A/C unit. An investigation to determine the true cause is underway. Mexican President Enrique Pena Nieto has already visited the scene of the blast. The President said his administration would “work exhaustively” to find a cause.
The Pemex headquarters complex employs thousands of people across several buildings. The largest is a 50-storey skyscraper, which was adjacent to the epicenter of the blast.
