Police arrested 20 Sudanese in connection with the caches, which contained grenades and ammunition.In a statement to reporters, Sudanese Foreign Ministry spokesman Ali Al-Sadiq voiced Khartoum's understanding of the procedures taken by the embassy. Yesterday, Britain had warned its citizens from traveling to Sudan because of fears that Western interests might be targeted.
