NAMIBIAN President Sam Nujoma arrived in Angola on Monday for talks with President Jose Eduardo dos Santos expected to focus on the worsening security situation along their countries’ borders. Nujoma arrived at Luanda’s airport late on Monday morning and immediately drove to the presidential palace for a meeting with dos Santos. Nujoma is expected to make a statement to the media late on Monday afternoon. Namibia’s northern border with Angola has become a war zone since December when Nujoma allowed Angolan government troops to use Namibian bases to attack Angolan Unita rebels. Since then, Unita has staged cross-border raids and planted land mines inside Namibia, while Namibian troops have chased suspected rebel fighters across the frontier.
