A bridge under construction in a new development in Dubai collapsed, killing seven workers and injuring 15, police said. The workers were employees of the Wade Adams Group, a Middle East-based contracting company, said N.M. Naushad, the company's human resources director. One of the survivors said the 30 workers were Indian. The bridge, spanning a small canal, was being built in Dubai Marina, a new residential and commercial development in this booming Gulf city-state. Police cordoned off the scene with tape to investigate, and ambulances took away the bodies of the dead and injured as their colleagues from the construction site stood around and watched, witnesses said.
