Five days after the mysterious crash of a Chinese airliner with 132 people on board, the identity of 120 dead has been clarified.

Guangxi Region Fire Department chief Zheng Xi said on Saturday that 114 passengers and 6 crew members had been accurately identified, according to the Beijing Aviation Administration.

No traces of explosives were found under debris during laboratory tests.

Meanwhile, Chinese authorities confirmed the deaths of all 132 inmates, according to the state news agency Xinhua.

"It is with great sadness that we announce that the 123 passengers and nine crew members aboard China Eastern Airlines flight MU5735 all died on March 21," the agency quoted deputy chief of the China Aviation Administration Hu Zhenjiang as saying.

Rescue work continued at the crash site in a hilly area near the southern Chinese city of Wuzhou.

However, the data flight recorder has not yet been found, only the voice recorder.

It was damaged but relatively complete.

Investigators hope the black box will provide technical information and other important data on the cause of the Boeing 737-800 crash.

Experts described the crash as very unusual.

The machine of the Chinese airline China Eastern Airlines suddenly went into a steep dive from a height of more than 8,000 meters on Monday, caught itself briefly, but then fell further and hit almost headfirst in the forest area.

Small pieces of debris were widely scattered around the crash site.

According to the authorities, several attempts had been made to contact the machine.

But the crew did not answer.

The signal from the MU5735 then disappeared around three minutes after the start of the dive.

On board the plane, which was en route from Kunming to Guangzhou, were 123 passengers and 9 crew members.
