Public emergency message released ahead of UK test
Further details have been released about the alert that will be sent to smartphones across the UK next week, to test a new public warning system.
A message with a siren at 15:00 BST on 23 April will say "in a real emergency, follow the instructions in the alert to keep yourself and others safe".
It will give a sound and vibration for 10 seconds even for phones on silent.
Phone users will have to acknowledge the alert before they can continue using their devices.
The alert system will be used to warn of extreme weather events, such as flash floods or wildfires. It could also be used during terror incidents or civil defence emergencies if the UK was under attack.
It is being sent to 4G and 5G mobile phones.
The full message will read: "This is a test of Emergency Alerts, a new UK government service that will warn you if there's a life-threatening emergency nearby.
"In a real emergency, follow the instructions in the alert to keep yourself and others safe."
"Visit gov.uk/alerts for more information.
"This is a test. You do not need to take any action."
Drivers are being advised not to look at or touch their phone until it is safe to do so, just as when receiving calls or messages.
"Getting this system operational means we have a vital tool to keep the public safe in life-threatening emergencies," said Oliver Dowden, the minister in charge of the system.
"It could be the sound that saves your life," he said.
Alex Woodman, from the National Fire Chiefs' Council, called on the general public to "play their part" in helping to keep people safe.
