"I will always love you in my heart," and "We miss you" are just two of the messages painted by children at the Sint-Lambertus primary school in the Belgian town of Heverlee in tribute to their teacher, Frank Van Kerckhove, also known as "Papa," who was killed in a bus crash in Switzerland earlier this week. The bus, which was carrying two classes of school children home from a skiing holiday, crashed into the concrete wall of a motorway tunnel. Twenty-eight people were killed in the accident and an investigation into the cause of the deadly incident is continuing.
