Thai Prime Minister Abhisit Vejjajiva has promised a "quick" investigation into the shooting of television cameraman Hiroyuki Muramoto, expressing belief that the military was not behind the shooting.
"The government fully cooperates with all the investigation. We urge the people who are doing this case -- the police and the special investigation department -- to investigate and come up with answers as quickly as possible without affecting obviously the accuracy of investigation," Vejjajiva said on Sunday.
"Personally, I don't believe that soldiers would shoot at the journalist and I believe that with all the pictures you have already seen, there were people with arms who caused a number of casualties during the April 10 incident," he added.
He said the soldiers are only to use live bullets for self-defense.
Muramoto, 43, was shot dead while recording violent clashes between security forces and anti-government protesters in Bangkok on April 10.
