The messaging platform WhatsApp has come back online after an outage that affected users around the world.
Meta, which owns WhatsApp, said the problem had been fixed but did not give a reason for the disruption.
People trying to send and receive messages on WhatsApp, which has about two billion users globally, began reporting issues just before 14:00 BST.
More than 12,000 reports were posted within half an hour, according to the service status website Down Detector. However, by about 16:00 BST service seemed to be returning for many users.
In a statement Meta said the problem had been resolved.
