BEIJING (AP) - Authorities in a southern Chinese city say a deadly explosion was sparked while workers unloaded banned caps for children's cap guns, and that the toll has risen to seven dead and 36 injured.
The Guangzhou Internet Information office said Wednesday that officials have ruled that the Tuesday blast was accidental.
The official Xinhua News Agency said police detained three people, including a Jordanian man who owned the product.
The blast went off in a truck container and then set fire to a nearby warehouse, sending up huge plumes of smoke.
It was the second deadly blast to strike China in two days. An explosion Monday on a busy street outside a school in the southern resort city of Guilin killed two people and injured 17, including 10 students.
