'Glitch' sparks false tsunami warning alert on US east coast

Some people on the east coast of the United States have received an alert on their mobile phones about a tsunami warning, which the National Weather Service said was meant to be just a test.

A routine US National Weather Service (NWS) test has resulted in a false push notification to mobile phones about a tsunami warning on America's east coast.

A glitch meant some people received what looked like an actual warning, NWS meteorologist Hendricus Lulofs said. The service is trying to sort what went wrong, he said.
