An agricultural tricycle rolled over into a roadside trench in northwest China's Gansu Province Sunday, leaving four passengers dead and the rest two aboard the vehicle injured, local authorities said. The accident occurred at about 7 a.m. as the tricycle fell into a five-meter-deep trench beside a country road in the Xigu district of Lanzhou, the capital city of Gansu, Xinhua quoted the district's work safety authorities as saying in a statement. The two injured are under medical treatment at a hospital. All the six aboard the tricycle are identified as migrant workers en route to a construction site. An initial investigation shows that the brake failure is to blame for the fatal accident. Police are further investigating the case.
