Uganda has said it has arrested 16 LGBT activists on suspicion of gay sex, which is punishable with life imprisonment, in what fellow activists called an escalating campaign against sexual minorities. The 16 men, believed to be aged between 22 and 35, were taken into custody late on Monday at the office of a sexual health charity where they all worked and lived, fellow activists said. It was not clear if the men had been formally charged nor when they might appear in court. A police spokesman said on Thursday officers had found lubricants, condoms and antiretroviral drugs at the charity, and had conducted medical examinations on all 16.
