At least two children have been killed after a gunman stormed a Catholic church in Minneapolis and opened fire as the parish school was holding its start-of-year mass.
The shooter, dressed in all black and reportedly armed with a semiautomatic weapon, 'pepper-sprayed' bullets through the stained glass windows at Annunciation Catholic Church this morning.
A heartbroken parent who attended the mass told The Star Tribune he fired '50 to 100 shots' as students and staff were sat in pews and 'killed two kids'.
'This is terrible,' the parent added. 'This is evil. I don't know how you defend against this.'
At least 20 people are feared to have been gunned down in the incident, although authorities have not yet confirmed how many victims there are.
