In the UK - the National Grid has confirmed that an explosion in Oldham yesterday - which killed a two year old boy - was not caused by a leak from its gas distribution pipes.
Police are now investigating whether the blast was caused by some sort of device. They therefore have said that they may be dealing with a murder inquiry.
Two-year-old Jamie Heaton died when a massive explosion tore through his home and that of a neighbour's house yesterday morning.
His mother Michelle survived - after she momentarily stepped into the yard to hang out washing to dry.
Her husband Kenny and two other children were not at home at the time.
