Severe challenges still persist

However, the interim government was still facing a serious of severe challenges and tough tasks on the eve of the referendum. Some experts believed the referendum could lead to more unrest.

Political factions outside the interim government may make trouble in the voting process and pushing for a government reshuffle, analysts said.

Kamchybek Tashiyev, the former Emergency Situations minister and leader of the Ata-Jurt (Fatherland) Party, said his party would not only reject the referendum, it also would call for a boycott on the vote.

The vote, under such chaos, would lead to a inevitable failure, he said, adding that only politicians needed the referendum.

The upcoming vote was also coupled with the threat of terrorism and extremism.

Although heavily stricken by the efforts of the North Atlantic Treaty Organization (NATO), Shanghai Cooperation Organization (SCO), the Collective Security Treaty Organization (CSTO) and the United States, the three evil forces had been waiting for chances to grow up. The riots in Kyrgyz were the one.

According to an investigation by the U.N. and the CSTO, some terrorists and extremists were behind the riots in southern Kyrgyzstan.

In a bid to stop the unrest, the interim government asked Russia to send troops to the riot-hit region. Moscow so far has stopped short of sending troops and saw the riots as an internal affair of Kyrgyzstan.

Can Kyrgyz's armed forces, which could not stop the large-scale unrest, fully control the situation and ensure the vote still remains a question.

In addition, Otunbayeva has rejected some calls from within her government to postpone the referendum. Rumors of postponing the vote were still widely spread in Kyrgyzstan.

Analysts predict the referendum would ultimately be announced as valid, but was likely to create more turmoil and protests.
