Japan said Thursday it hopes to receive further information from Thailand about the death of a Japanese cameraman shot more than three months ago during protests in Bangkok. Hiroyuki Muramoto, 43, of the Thomson Reuters news agency, was shot in the chest by an unknown gunman on April 10 while covering unrest involving Thai troops and anti-government 'Red Shirt' protesters. 'We hope that more detailed information may be forthcoming,' Japanese deputy press secretary Hidenobu Sobashima told reporters on the sidelines of the ASEAN Regional Forum (ARF) security dialogue. He said Japan understands the Thai government is doing what it can on the case but if foreign ministers from the two countries meet at the ARF, 'it may be natural to express the concern once again.' Shortly after Muramoto's death Japan's Foreign Minister Katsuya Okada said his ministry 'would make diplomatic efforts to call on the Thai government to firmly pursue the facts of the case.' Thailand's Foreign Minister Kasit Piromya declined to comment to selfnews. Muramoto was one of two foreign cameramen killed during the Bangkok unrest in April and May. Ten other journalists were wounded. In a report this month, the watchdog Reporters Without Borders called on Thai authorities to publish final reports on the death of Muramoto and Italian photographer Fabio Polenghi 'as soon as possible.' They were among 90 people -- mostly civilians -- killed in the April and May unrest surrounding the protests, which ended in a military crackdown. A Thai inquiry led by a former attorney general has been appointed to investigate the loss of life, but Kanit Nanakorn said his aim was to establish facts rather than responsibility.
