With the peace process in Cote d'Ivoire running into fresh difficulties and the rebels once more resisting pressure to disarm, international mediator and South African president Thabo Mbeki has called the warring factions to a new summit. "The president proposed the 25th and 26th (of June) as the dates but all the parties can't make it. Therefore arrangements are being made to find another suitable date," Mbeki's spokesman Bheki Khumalo was quoted as saying by Agence France Presse.
