The police identified the attacker in Saturday’s shooting at the synagogue, Chabad of Poway, as John Earnest, 19. They said he had written a manifesto echoing the white supremacist views promoted by gunmen who attacked a synagogue in Pittsburgh last year and mosques in Christchurch, New Zealand, in March.

Quotable: “We can disagree about all sorts of important things, even ultimate things, but surely every person ought to agree that no one should be gunned down in worship,” said Russell Moore, the president of the Ethics and Religious Liberty Commission of the Southern Baptist Convention.

Unheeded warnings in Sri Lanka

A newly revealed memo, dated 12 days before a series of suicide bombings on Easter Sunday, warned the country’s police chief of an imminent terrorist attack.

The memo adds to a growing paper trail of detailed warnings that cast doubt on President Maithripala Sirisena’s claims that he did not know the attack was coming.

The Islamic State has claimed responsibility for the attack, and, since the bombings, anti-Muslim feeling has been rising across Sri Lanka. Today, Mr. Sirisena banned “all forms of clothing that cover a person’s face and prevents them from being identified.”

Catch up: The Islamic State said its fighters were among those killed in a raid in eastern Sri Lanka that left 15 dead and that wounded the wife and child of Zaharan Hashim, who is believed to have been behind the bombings.
