After holding talks, Tuesday, September 25, with David Hale, the United States Under Secretary of State for Political Affairs, the German diplomat met the same day with the Algerian Minister of Foreign Affairs, Abdelkader Messahel. The UN Secretary-General's personal envoy for Western Sahara also spoke with Ismail Ould Cheikh, Mauritania's Foreign Affairs Minister, as well as Belgian Foreign Minister Didier Reynders.
