An unknown man wielding a knife at a Belgian nursery school killed at least 2 children and one adult today, the BBC reports. A dozen or more were said to be injured in the attack northwest of Brussels. The attacker, wearing black-and-white face paint, fled by bicycle, says the Times of London. The children have been evacuated and police have arrived; some reports say the man has been arrested. “Ten, 15, 20 are injured, I don't know,” an emergency worker told Reuters.
