Justin Bieber axes Instagram amid war with Selena Gomez fans

Justin Bieber has gone nuclear in his war with fans of ex-girlfriend Selena Gomez by deleting his Instagram account.

Bieber posted several pictures of himself with Sofia Richie over the weekend. He responded to negative comments by captioning one photo, "I'm gonna make my Instagram private if you guys don't stop the hate this is getting out of hand, if you guys are really fans you wouldn't be so mean to people that I like."
