A BOMB explosion outside a fertility clinic in Palm Springs, California, killed one person and injured four others in what the FBI today called an “intentional act of terrorism.”

The suspect, believed to have died in the blast on Saturday, attempted to record or livestream the attack, which devastated the American Reproductive Centres clinic.

“Make no mistake: This is an intentional act of terrorism,” said Akil Davis, head of the FBI’s Los Angeles field office.
