A bridge collapsed in northeast Taiwan on Tuesday morning while an oil tanker truck was crossing it, sending the truck crashing onto fishing boats and launching rescuers on a desperate search for missing victims, according to local officials and news reports.

At least a dozen people were injured, including the truck’s driver and several fishing boat workers, the authorities said.

The Nanfang’ao Bridge, about 150 yards long, fell around 9:30 a.m. local time, according to Taiwan News. Hsu Kuo-yung, Taiwan’s interior minister, told Formosa TV that 10 people were initially sent to hospitals, six of them with serious injuries. Two rescue workers were also injured.

The tanker truck was moments away from crossing the bridge when it plunged tail-first toward the water, catching fire after it landed, according to Focus Taiwan, a local news channel.
