DHAKA: Fires are still burning at the site of two massive explosions in the Chinese city of Tianjin, some 36 hours after the blasts.

A team of military chemical experts is testing for toxic gases at the scene and rescuers have been ordered to wear protective clothing, state media said.

At least 50 people died and hundreds were injured, 71 critically, in the explosions on Wednesday evening.

Meanwhile, search teams found a survivor in the debris on Friday, BBC reported

The survivor was named as 19-year-old firefighter Zhou Ti, state-run news agency Xinhua said.

Officials said earlier that 17 firefighters were among the dead and China's Ministry of Public Security added that, as of Thursday afternoon, 18 others were still missing.

Tianjin's fire chief Zhou Tian told reporters on Friday that more than 1,020 firefighters and 140 fire engines were still battling flames at the scene.

Fire crews were already at the scene when the explosions took place, having been called to reports of a container fire.
