Police in Texas have expressed their relief that pupils were not at school when a fertiliser plant exploded in the town of West, Texas.
As shown in the map above, the West Fertilizer Co neighbours the West Independent School District and the West Middle School.
The West Rest Haven just to the north of the school suffered severe destruction.
"Thank God school was out," said Waco Police spokesperson William Swanton of the blast, which happened at around 8pm local time.
A major rescue effort is ongoing in a Texas town devastated by a fertiliser plant explosion that has been likened to a nuclear bomb blast.
A huge explosion at a fertiliser plant in the Texan town of West has injured more than 160 people and caused widespread destruction.
