The Wall Street Journal: Shaken by terror attacks, France vows to step up security

PARIS — French authorities pledged to boost security at high-profile events this summer after the slaying of a priest by Islamist radicals, as officials deepened their investigation into the latest terror attack to stun Europe.

Investigators have tentatively identified a second suspect in the priest’s killing as a French resident whom security services had previously flagged as a terror threat, officials familiar with the investigation said. Authorities had been searching for him after he recently disappeared from his home in Aix-les-Bains in southeast France, officials said. But the authorities warned he has yet to be formally identified.

Prosecutors identified the first suspect in Tuesday’s killing as Adel Kermiche, a 19-year-old who had been arrested twice for attempting to reach the battlefields of Syria and Iraq.
