The government of Sudan has suspended contact with an umbrella opposition group, the National Democratic Alliance (NDA), because it has allowed a rebel group from war-torn Darfur to join its ranks. The government spokesman, Sa'id Khatib, told IRIN on Monday that the government had suspended all contacts with the NDA "about four days ago", because the Sudan Liberation Army (SLA) was now one of its members. "We have suspended all contacts until the NDA clarifies why it has brought a fighting group on board," he said. "Fighting and dialogue do not go together."
