BANGKOK, May 5 (Xinhua) -- Thailand's Council for National Security (CNS) chairman Sonthi Boonyaratkalin told people on Saturday to ignore a statement by his own CNS deputy secretary-general Saprang Kalayanamitr that British police had found a Bangkok terrorist manual in a London apartment.

    Sonthi said rumors about unrest in the country are a political tactic of "some groups with agenda," so the people should not worry about it. He asked people to place their trust in the national security agencies who will safeguard them, reported the web edition of the Bangkok Post newspaper.

    He added the government, the army and the CNS do not neglect such remarks, and they are prepared for possible violence in the country.

    However, Sonthi said that it is the responsibility of the Foreign Ministry to check facts and find information on the issue of the alleged terrorist manual.

    He added that he believed Saprang's remark should not hurt the credibility of the CNS.

    The report of a possible terrorist attack in Bangkok stemmed from remarks by Saprang during a lecture on Bangkok security given to Bangkok Metropolitan Administration's district directors on Thursday.

    During the lecture, he said British police had found a copy of a document outlining a plan to launch terrorist attacks in Bangkok. They found the plan in a London apartment.

    But Saprang Friday clarified the document in question was old information, dating back to the end of the Cold War. It warned of terrorist attacks in several cities, including Bangkok.

    However, no other diplomatic or military source could confirm such a book existed. Opposition members in Thailand demanded that the government ask the British government for further details.
