The recent bomb blasts in Burma, including in former capital Rangoon could be a plot hatched by the junta to reunite its military, in which deep fissures developed during the crackdown on protesters in September, analysts said.

Since last Friday, three bombs have exploded in various places in Burma including its commercial hub Rangoon and its new administrative head quarters Pyinmana, killing at least two and injuring five people, the government-owned New Light of Myanmar said.

The government reacted with alacrity pointing fingers at the Karen National Union (KNU) an ethnic Karen armed rebel group based along the eastern borders, which could be another way of finding a 'common enemy' to reunite the military after the reported rift following the brutal treatment meted out to protesting monks in September, said Htay Aung, a Thailand based Burmese analyst.

"It is like a tradition in the army to find a common enemy for unity as there are disagreements among themselves. Earlier they [the junta] would declare the Burma Communist Party [BCP] as a common enemy and later the west. Now it looks like they are targeting the KNU in order to divert attention," Htay Aung said.

On Friday a small bomb exploded at the toilet of Pyinmana railway station, near the junta's new jungle capital Nay Pyi Taw, killing one woman. The same evening, another bomb exploded in a field in Phyu town of Pegu division, killing one person and injuring three women and a child, the New Light of Myanmar said.

Further on Sunday, a bomb exploded near the Rangoon railway station injuring a woman, the newspaper said. The newspaper said all three incidents were perpetrated by KNU members and warned the people to be aware and to inform of any suspects.

However, the KNU denied any involvement in the three blasts and rejected all allegations as false and biased.

Pado Manh Shar, general secretary of the KNU said, "Our policy is not to harm innocent people. And since we did not give any orders to carry out such activities, we strongly reject all this allegations."

Win Min, another Burmese analyst in Thailand said, while the culprit behind the bomb explosions cannot be confirmed, the junta has been quick in blaming the KNU in an effort to evoke a sense of patriotism among the army and bring back unity.

"If the military feels that there is an enemy, it is easier to unite. So, it might be possible that the junta wants to inculcate this sense by declaring the KNU as a common enemy of the military," Win Min added.

The Burmese military, which has been ruling the country continuously for more than 45 years, was reported to have suffered a rift among low raking soldiers over its high handedness on protesters led by monks in September.

While the differences and the power struggle between Burma's two top military generals, Snr. Gen Than Shwe and Vice Snr. Gen Maung Aye, is being reported for sometime, the September brutality brought about the first signs of rift the military suffered among low ranking soldiers, who were reluctant to brutally suppress the highly revered Buddhist monks.

"If any group [armed insurgents] wants to explode bombs, why would they want to do it in toilets and in dustbins? They would directly place their bombs near their target. So, I think the junta has purposely placed the bombs," Htay Aung added.
