At least 60 people were injured Friday in a bank in northwest China where a former employee detonated a homemade bomb fuel in the room where they held a staff meeting with all these office workers, local media reported.

The explosion occurred about 8:30 am (0:30 GMT) in a rural bank in a district of the city of Wuwei, in the northwestern province of Gansu, and former employee who caused it fled the scene, according to the official People's Daily. "

The provincial government confirmed that the wounded, 19 of them serious and over 40 minor, have been transferred to the district hospital, while police have launched an investigation into the incident.

More than 10 people jumped from fourth floor windows, where the meeting was held, to escape the flames, they said some witnesses cited by Xinhua.
