A spate of weekend bombings on Zanzibar, which hosted visiting German President Johannes Rau on Monday, hit the homes of local political and religious leaders and a restaurant being used by Western diplomats, police said. There were no casualties from the homemade bomb blasts at the house of Zubeir Ali Maulid, a cabinet minister in the Tanzanian semi-autonomous island's government, and the home of Zanzibar's Mufti and top Islamic leader, Harith bin Khelef, said police spokesperson George Kizuguto.
