Chettha on defence

Chettha says he's certain of his information and the authenticity of the video, although he can't be "100-per-cent certain".

He says releasing the video was not done for his own political gain. Negotiations were conducted without the involvement of any government or military staff.

Wait and see

Chettha wants people to wait and see if violence in the deep South reduces significantly.

Former intelligence chief Pallop Pinmanee remains unconvinced, however. He says many things are "not right", including nobody knowing the identity of the three men on the video, or the group they claim to represent.

Pallop adds that an unconditional ceasefire "sounds too good to be true". He cannot think of such a thing anywhere in the world having happened before.

Meanwhile, a 47-year-old man was ambushed and shot while riding his motorcycle on the Wangpaya-to-Kota Baru road in Yala. He remains in a stable condition in hospital.
