LIBYAN leader Muammar Gadaffi wrapped up a three day visit to Sudan with an appeal to Sudanese opponents abroad to come back home. “I am ready to guarantee their safe return,” he told Sudanese students at a meeting just before heading for the airport for his flight home. “Force cannot solve any problem and all problems can by settled with an exchange of opinions,” he told them. He pledged to exert his “utmost efforts to promote unity and accord” in Sudan. Sudanese President Omar al-Beshir to do so instead. Beshir hailed the outcome of Gadaffi’s visit which he said had discussed closer cooperation between the two countries. Gadaffi was accompanied to Sudan by a delegation of over 800. He needed several planes to bring with him not only their luggage, but also a number of official cars and a big tent which he used inside his residence, a splendid guest palace overlooking the Blue Nile.
