US police say a gunman has opened fire at a synagogue in California, leaving one woman dead and three other people injured.
A 19-year-old man has been arrested after the attack at Poway, north of the city of San Diego.
Reports said the synagogue had been hosting a Passover celebration when the shooting took place.
Police have not suggested a motive but US President Donald Trump said the attack “looks like a hate crime”.
The shooting comes six months after a gun attack killed 11 people at the Tree of Life synagogue in Pittsburgh. It was the worst anti-Semitic attack in recent US history.
