Description:Belgium's historic city of Leuven holds a church ceremony to honour the victims of last week's tragic bus crash. Thursday's joint funeral was held to remember the lives of seven of the children who died in the accident, all of whom were aged 11 or 12 and attended the Catholic St. Lambertus school in a nearby town. Belgium's Prime Minister stood outside the church to welcome international politicians and Belgian monarchs who came to attend the ceremony.(1:18)
