PORT-AU-PRINCE, Haiti (AP) — Gangs attacked two upscale neighborhoods in Haiti’s capital early Monday in a rampage that left at least a dozen people dead in surrounding areas. Gunmen looted homes in the communities of Laboule and Thomassin before sunrise, forcing residents to flee as some called radio stations pleading for police. The neighborhoods had remained largely peaceful despite a surge in violent gang attacks across Port-au-Prince that began on Feb. 29.
