The Sun quotes an Iraqi soldier:
Militants of the IG detonated a bomb fixed on the body of a four-year-old boy to a child, using a remote control. The boy's father, captivated by the militants, was executed last week.

For obvious reasons, it is not yet possible in any way to verify the accuracy of the information that the IS militants used a four-year-old child as a suicide bomber. However, after numerous publications by the militants themselves about executions, including the sensational execution by the fighter of his own mother, the publication The Sun does not look like a plain newspaper duck.
