In Norway, a 37-year-old Danish man used a bow and arrow to attack people in a small town west of Oslo Wednesday, killing five people and wounding two others. Police described the suspect as a Muslim convert who had previously been flagged for “radicalization,” but authorities say the motivation for the attack is still unknown and that he is thought to have acted alone. Wednesday’s attack prompted police across Norway to carry firearms. Norwegian police are usually unarmed. It was Norway’s worst attack since a far-right white supremacist killed 77 people a decade ago.
