At least one person is dead and four others injured in a Palm Springs explosion outside of a fertility clinic, Assistant Director Akil Davis of the FBI said Saturday.

The investigation into a deadly explosion — deemed "an intentional act of terrorism" — at the site of a Palm Springs fertility clinic Saturday is focused on a "person of interest" with no further imminent threat to the public, the FBI said.

A suspected bomb blast that authorities believe was 'an intentional act of terrorism' outside a Palm Springs fertility clinic left one person dead and additional people injured.
