Ningbo blast: Police says no human error behind the incident

A day after a powerful blast hit China's port city of Ningbo, police has ruled out the possibility of a human error behind the incident in which two people were killed and many injured.
The explosion occurred early morning at a demolished factory in Jiangbei district of Ningbo City in Zhejiang province and also left two persons missing.
It was country's worst industrial explosion in three years which also damaged nearby buildings and vehicles.
The Chinese police today ruled out the possibility of a human error behind it and said further investigation was required into the cause of the blast, state-run People's Daily reported.

Ningbo is one of China's major international cargo and container shipping ports.
China had a number of industrial accidents in the course of its massive economic growth.
Today's explosion resembled a series of explosions in 2015 in Tianjin port city which ripped through a warehouse, leaving 165 people dead, eight missing and 798 injured.
The majority of those killed were firefighting crews who had gone to douse the flames.
