By infiltrating into the Sudanese capital Khartoum and launching attacks, a major rebel movement in the western Sudanese region of Darfur could get nothing but grievous losses and unanimous condemnation by the international society, local analysts affirmed on Sunday.

They described the assault carried out by the rebel Justice and Equality Movement (JEM) at Omdurman in northwestern Khartoum as "a politically suicide attack" and "a military unvalued adventure."

The Sudanese government termed on Sunday night the Saturday's attack by the JEM rebels as a "terrorist operation for sabotage," announcing that this operation had "finished."

"This terrorist operation for sabotage was plotted by Chad and carried out by JEM leader Khalil Ibrahim," Kamal Obeid, the minister of state in the Sudanese Ministry of Information and Communications, told reporters.

The JEM is believed to have the most powerful forces among rebel groups in the western Sudanese region of Darfur, which amount to over two dozens.

The Sudanese government announced on Saturday evening that the army and the police had crushed the attempt of the JEM rebels to infiltrate into the capital and carry out sabotage activities there, killing and capturing a number of the infiltrators.

It was the first time for rebels in Darfur to enter Khartoum and launch attacks there since bloody conflicts erupted in the western Sudanese region neighboring Chad in February, 2003.

Sadig al-Madi al-Mahdi, a presidential adviser and the chairman of the Umma Party-Collective leadership, told Xinhua that this attack was "a desperate attempt aimed at snapping the public opinion."
