Bashir, in a speech from the Sudanese embassy in Saudi Arabia broadcast on Sudan's Blue Nile TV, also said he was in "perfect health" after undergoing surgery in the Gulf kingdom.
Sudan last month accused Israel of carrying out an air strike on the Yarmouk weapons plant in the south of Khartoum, causing a blast that killed four people.
