The Center for Resolution of Emergency Situation (CRES) made the ultimatum on a television program, after it assigned police Sunday to persuade the red-shirt protesters to leave the rally site by 15:00 hours on Monday.

The CRES said the anti-government protesters "must leave the rally site immediately" and any violation against the CRES order will face a two-year prison sentence.

The rally site is now the dangerous zone, the CRES added.

The red-shirt protesters have been camped out at the Rathchaprason Intersection, a central Bangkok commercial district, since early April.

The main rally site was cordoned off on Thursday night prompting clashes between government troops and protesters and leaving at least 35 people dead.

The demonstrators have vowed to continue the protest which has lasted for over two months until prime minister Abhisit Vejjajiva stepped down.
