A car bombing injured four people and damaged a fertility clinic and nearby buildings in Palm Springs, California

The blast on Saturday in Palm Springs, California, injured four people and severely damaged several buildings, authorities said.

The car bombing outside a California fertility clinic that killed one person and injured four others appears to have been driven by anti-natalist ideology, according to two senior law enforcement officials briefed on the incident.

Authorities are investigating what appear to be radical views that Guy Edward Bartkus expressed online in the months before Saturday’s attack.

At a press conference, Akil Davis, FBI assistant director in charge of the Los Angeles field office, said the bombing was “an intentional act of terrorism.”
