A senior child rights monitor at the rights group Licadho said Tuesday that the first period of 2009 saw an increase in the number of child rape cases reported compared with the same period last year. "There were 31 cases reported in the first three months of 2008, and now there are 65. So that makes us worry," Pean Rathamanith said, adding that Kampot, Battambang, Kandal and Phnom Penh have the highest numbers.
