Security for Thai Prime Minister Surayud Chulanont has been stepped up, the military said Thursday, Jan.4, 2007, as political bickering escalated over who was to blame for New Year's bombings that killed three people. A former prime minister, Chavalit Yongchaiyudh, responding to insinuations that he may be linked to the eight small blasts in and around the Thai capital of Bangkok on Dec. 31, 2006, accused the military of mishandling the case, which he described as an inside job.
