TIANJIN, China—Rescuers pulled out a firefighter who was trapped for 32 hours after responding to a fire and huge explosions in the Chinese port city of Tianjin as authorities moved forward gingerly Friday in dealing with a fire still smoldering amid potentially dangerous chemicals.
A rapid succession of explosions late Wednesday — one equal to 21 tons of TNT — killed at least 50 people, injured more than 700 and left more than a dozen firefighters missing. They were sparked by a fire at what authorities said were shipping containers containing hazardous material. They struck a mostly nonresidential warehouse district late at night — otherwise the death toll could have been much higher.
