Three students have been killed in an explosion in a laboratory at Beijing Jiaotong University, the capital’s fire services said. The incident happened at around 9:30 am on Wednesday when the students were carrying out sewage treatment experiments in a laboratory building on the east campus, the fire services said in a statement.
“The incident caused the death of three students who participated in the experiment,” the statement said. The cause of the incident was not immediately known and the authorities were investigating. Video online showed the building was engulfed in dark smoke while flames were also visible. Eight fire crews and 30 fire engines were sent to tackle the blaze.
Some students told The Beijing News that they were taking an exam in a neighbouring building and heard an explosion before the room started filling with smoke. They were then told to leave the building. One student said she heard several loud bangs after leaving the building. A statement from the university said the fire was brought under control within an hour and there were no other casualties. The area has been closed for investigation.
