An alliance of opposition parties says it's withdrawing from the new government created only days ago by self-appointed President Michel Djotodia.

Djotodia, whose rebel fighters overthrew the country's president of a decade about a week ago, had announced a new list of government ministers late Sunday.

However, the opposition parties say they were disappointed to learn about the appointments from state radio like everyone else.

Prime Minister Nicolas Tiangaye, a longtime opposition leader, said Tuesday that the other opposition members couldn't be forced to participate.

Tiangaye is leading a delegation from Central African Republic to neighboring Chad on Wednesday, where regional leaders are due to discuss the country's ongoing political crisis.

Central African Republic's new president says he plans to rule until elections in 2016.
