Partial results in Uganda's chaotic election on Friday gave veteran president Yoweri Museveni a solid lead as the US urged him to "rein in" the police after his main challenger was detained for the third time this week. The police raid came as people continued to vote at dozens of polling stations in the wider Kampala area, where voting was extended in 36 sites for a second day after delays on Thursday that Commonwealth election observers called "inexcusable". While Museveni maintained his lead in the presidential tally, at least 17 of his ministers lost their parliamentary seats, among them defence minister Crispus Kiyonga — who is spearheading regional efforts to end the political crisis in Burundi — and attorney general Fred Ruhindi.
