TEHRAN, Iran—Rescuers dug through debris Tuesday of a building collapse in southwestern Iran that killed at least 11 people, fearful that many more could still be trapped beneath the rubble as authorities arrested the city’s mayor in a widening probe of the disaster.
The collapse Monday of an under-construction 10-story tower at the Metropol Building exposed its cement blocks and steel beams while also underscoring an ongoing crisis in Iranian construction projects that has seen other disasters in this earthquake-prone nation.
