Explosion rocks Amsterdam Jewish school in wave of antisemitic violence - CNN

An overnight explosion damaged the outer wall of a Jewish school in Amsterdam and officials called it a targeted attack on the Jewish community, joining a series of antisemitic incidents across Europe. The San Diego mosque shooting, which authorities are treating as a possible hate crime, reinforces concern that religious institutions of different faiths are being targeted and may prompt greater international forensic and intelligence cooperation. Authorities in Europe and the U.S. are likely to compare methods, devices, and communications to assess whether attackers are sharing techniques or inspiration.
