Chinese firefighter Zhou Ti is treated in Taida Hospital in north China's Tianjin municipality Friday, Aug. 14, 2015. Rescuers pulled Zhou from an industrial zone about 32 hours after it was devastated by huge blasts in China’s Tianjin port. Meanwhile, authorities are moving gingerly forward in dealing with a fire still smoldering amid potentially dangerous chemicals.

TIANJIN, China — State media say the death toll from massive blasts in the Chinese port of Tianjin has risen to 104.

The new toll Saturday came rescuers scour the warehouse district devastated by a fire and series of explosions late Wednesday at a warehouse for hazardous chemicals.

Rescuers also found an additional survivor Saturday as authorities evacuated much of the area to clean up dangerous chemical contamination. Several additional small explosions rocked the disaster zone as the clean-up continued.

The toll includes at least 21 firefighters — making the disaster the deadliest for Chinese firefighters in more than six decades. Several remain missing.

A total of 720 people were injured in the disaster in Tianjin, a key port and petrochemical hub east of Beijing.
