LONDON: Millions of mobile phones across the UK blared a siren sound at the same time on Sunday as part of government efforts to better prepare for national emergencies.

The nationwide drill caused England’s third ODI cricket match against South Africa to be paused while kick-off for a rugby league match was pushed back to avoid disruption.

At 3:00 p.m. (1400 GMT), phones and tablets emitted the noise and vibrated for about 10 seconds, while users also received a message saying it was just a test.

It was only the second test of the country’s national emergency alert system following the first in 2023.

The government had in recent weeks embarked on a publicity drive to minimize any shock caused, including through announcements at rail stations and signs on motorways.
