Residents displaced by the massive fertiliser plant explosion in Texas have been told by officials that tanks on the site are leaking gas and causing small fires.
The fires are reported to be contained, but they are preventing those who live nearby from returning to their homes in the town of West.
Paramedic Bryce Reed, also a spokesman for West said he leaks were caused by tanks damaged by heat and had triggered small fires. He said no further evacuations were necessary.
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.
