Between five and 15 people are thought to have been killed by a huge explosion at a US fertiliser plant that witnesses said was "like a tornado".
More than 160 people were injured as dozens of homes and buildings were destroyed in the evening blast near Waco in the US state of Texas.
Emergency services are still going from home to home trying to find survivors.
