Khartoum: Sudan's ruling party on Sunday warned there will be more violence in Darfur if the country's president is indicted for crimes against humanity and genocide as hundreds of people rallied in Khartoum to show their support for the longtime leader.

A prosecutor at the International Criminal Court is expected to seek an arrest warrant on Monday charging President Omar Al Bashir with orchestrating violence in Darfur that has left hundreds of thousands of people dead since 2003.

In a statement, the ruling National Congress Party called the case against the Al Bashir "irresponsible cheap political blackmail" that has no legal basis.

It also warned there would be "more violence and blood" in Darfur if an arrest warrant is issued against the president, state TV reported.

Al Bashir huddled with ministers and advisers on Sunday, weighing how the government would response to any action taken by the ICC. Sudan has also asked the Arab League for an emergency meeting of Arab foreign ministers.

Outside the meeting, hundreds of Sudanese demonstrated to show their support for Al Bashir.
