While getting text messages from your service provider is incredibly annoying, it can sometimes be a complete life-saver. That is, unless you happen to be a suicide bomber. Below is a report concerning a bombing attempt in Russia which was foiled by an incoming text. From the Telegraph:
The unnamed woman, who is thought to be part of the same group that struck Moscow's Domodedovo airport on Monday, intended to detonate a suicide belt on a busy square near Red Square on New Year's Eve in an attack that could have killed hundreds.

Security sources believe a spam message from her mobile phone operator wishing her a happy new year received just hours before the planned attack triggered her suicide belt, killing her but nobody else.
Usually the suicide bombers are assisted by a handler, who waits for the right moment to inflict maximum casualties before sending the bomber a text message in order to set off the explosives. Seems like this terrorist was careless and had forgotten to switch off her phone until the very last minute.
