Ugandan President Yoweri Museveni met rebel negotiators of the Lord's Resistance Army (LRA) for the first time on Saturday to try to revive talks aimed at ending one of Africa's longest and most brutal wars, Reuters reported. No details were immediately available about what was said during the unscheduled private half-hour meeting at south Sudan's parliament building. LRA officials made no comment as they left. But in a speech to south Sudan's parliament, Museveni hinted at his frustration in dealing with the insurgents, who he often denounces as fugitives, terrorists and bandits. Museveni hailed southern Sudanese Vice-President Riek Machar, who is the chief mediator at Ugandan peace talks, as a "very, very persistent person". "He knows how to deal with the unserious LRA," he told parliament.
