KHARTOUM (AFP) - Sudanese forces have killed six bandits who kidnapped 19 European tourists and their Egyptian guides in a remote desert nine days ago, a top official told AFP on Sunday. "Sudanese forces followed the tracks of the kidnappers from Jebel Uweinat (a mountain range on the Sudan-Libya-Egypt border) and found them on the Chad border," presidential advisor Mahjoub Fadl Badri said. "Sudanese forces killed six, including the commander of a Darfur rebel group, and arrested two," he said. "What the (captured) kidnappers say is that the hostages are still in Chad, they put them in a hideout and are still negotiating about them, but we have no details whether the Chadian army has moved in." Earlier, an official had said the 11 tourists and eight Egyptians, who were snatched at gunpoint during a desert safari on Sept 19, were "all well" and to appeared to be moving from Sudan towards Egypt. An Egyptian security official told AFP that the kidnappers and German negotiators had agreed to a deal but that "negotiations were still ongoing to work out details." The kidnappers have demanded that Germany take charge of payment of a 8.8-million-dollar ransom, an Egyptian security official told AFP on Thursday. They also want the ransom to be handed over to the German wife of the tour organiser. The five Italians, five Germans, and one Romanian plus eight Egyptians, two guides, four drivers, a guard and the organiser of the tour group, were kidnapped on a desert plateau famous for prehistoric cave paintings, including the "Cave of the Swimmers" featured in the 1996 film "The English Patient." The independent Egyptian daily Al-Masry al-Yom quoted an anonymous German official on Sunday as saying negotiations between German negotiators and the kidnappers had ended with the bandits' agreement to release the hostages soon. An official at the German embassy in Cairo declined to comment. Germany has kept quiet about its role in any negotiations, saying only that it has set up a crisis team.
