Did Thai PM Samak order attack dogs to be used on Hmong refugees?

Blogger Fonzi has posted a report from a source claiming the Thai PM ordered that dogs be used against Hmong refugees. Money quote:

“Reliable and multiple eyewitness sources in Thailand have reported that Thai military officials, at the apparent direct order of Prime Minister Samak Sundaravej, in preparation for his upcoming trip to Laos, used teams of military attack dogs led by armed soldiers to intimidate and maul some 12-13 Lao-Hmong refugees at Ban Huay Nam Khao detention center as brutal preparation before forcing them back to the Communist regime,” stated Philip Smith, Executive Director, of the Center for Public Policy Analysis, in Washington, D.C.

Bangkok Pundit dug into this story further on his blog. Whether or not Samak personally ordered the use of dogs remains an open question in his view. Bangkok Pundit adds that there might well be a connection between repatriation of the Hmong and an energy deal that Thailand recently signed with Laos. He writes: "Now, this could just be a coincidence, but I have suspicions there was a link between the swapping of the energy for the Hmong given the timing."
