Facebook triggers false bomb scare

Facebook sparked fear - and anger - among Thailand's social media users after its Safety Check feature triggered a false bomb alert in Bangkok.

The check-in feature allows users to signal to friends that they are safe after an event in their area such as a terror attack or natural disaster.

But it appeared to misfire late on Tuesday, creating an alert called "The Explosion in Bangkok" that said a blast in the capital had been confirmed by "multiple sources".
