The chairman of Cambodia's Commission to Conserve Mekong River Dolphins and Develop Eco-Tourism, Touch Seang Tana, said Wednesday he had received a written explanation from WWF about its recent report but was yet to decide on its merit. The report, released last month, claimed pollution in the Mekong was in part responsible for the deaths of 88 Irrawaddy dolphins since 2003 and prompted a harsh rebuttal from Touch Seang Tana, who dismissed the report as full of "lies". He said Wednesday that he was "too busy" this week to reply to the organisation, but that he would send a letter to them next week seeking clarification on certain points.
