A man and a woman were killed on the spot and the injured persons, including 10 students, were taken to a nearby hospital, official media reported.

Footage on the state television CCTV showed many damaged vehicles lying in front of the school.
The explosion struck about 7:10 a.m. as the students were arriving at the Balijie Primary School in Lingwu County of Guilin, a resort city in Guangxi.
Witnesses told Xinhua news agency that a man riding a three-wheeled motorcycle passed the entrance to the school when the blast took place.

"First, the motorcycle caught fire and then exploded with a tremendous noise that could be heard from far, far away," a witness told Xinhua.
A dozen motorcycles were scattered around the blast site and the window panes of cars and stores by the school were damaged.
