The headmaster approached the lectern and called for silence, "Students! A terrible tragedy has struck the wizarding world. This evening, there was an attack on Diagon Alley by Death Eaters. Many shops were burnt, few people injured, and few others lost their lives. Classes for the week have been cancelled. Students whose family members were injured or lost their lives are allowed to return home. You shall be contacted by your respective heads. You may now return to your dorms. Prefects!"
