Kathmandu, June 8 :    Kathmandu, June 8:  While his story of the palace tragedy has been generally received here with much scepticism, Captain Rajiv Shahi seems to have rattled both the army and the government by giving out his 'eyewitness account' at a news conference yesterday. There were unconfirmed reports that the army authorities were considering action against him for not having taken permission from them for speaking to the media. Captain Shahi, son-in-law of slain King Birendra's brother, Dhirendra, is an army doctor. But political sources doubted how far the army could go if Shahi had the permission of the palace to speak out. These reports also suggested that action could be taken against the military hospital superintendent for allowing the news conference inside the hospital complex at Chhauni. There was, however, no confirmation from either the army or the government about these reports. Apart from the question of the propriety of calling the media over to the hospital, the army authorities were reportedly upset over the manner in which the hospital security was breached. Several of the injured of Friday night's palace shooting are still in the hospital. But Nepal's foreign minister, Chakra Prasad Bastola, today expressed the government's displeasure at Shahi's action. In an interview to a television channel he said Shahi should not have spoken to the media at a time when the two-member probe committee, headed by Chief Justice Keshav Prasad Upadhyay, was about to start work on unravelling the mystery of the palace murders. Shahi's action also came in for criticism from a breakaway Maoist group, Sanjukta Jan Morcha, which cited his news conference as 'one more example' of the 'conspiracy in the world media' to accuse Dipendra of the murder. 'He was not the murderer,' Leelamoni Pokhrel, Morcha leader, said unambiguously, while addressing the first rally by a political party since the royal tragedy at Patan near here. In its first public pronouncement on the post-massacre situation today, the army cautioned that 'anti-national campaigns and false propaganda could have an adverse effect on national security in this sensitive situation'. In a full-page advertisement in the largest-circulated Nepali daily, Kantipur, whose editor Yubhraj Ghimire, was arrested along with the publisher and the managing director two days ago, the Royal Nepal Army greeted King Gyanendra and reminded the people that the army had always done its duty to 'protect the sovereignty, geographical unity and national independence under the leadership of the king'. Analysts here read in the message an attempt to silence critics who had also pointed an accusing finger at the army for its failure to prevent the palace massacre. It was also said to be a move to set at rest speculation that there were differences within the army and between the army and the new palace dispensation, not only over the probe into the massacre, but also over the future of democracy. It is public knowledge here that the present king had differences with his brother, the late King Birendra, over the role of democracy, with the former having taken a hardline position during the 1990 democracy movement.
