Beijing: An explosion shook a chemical plant in the eastern Chinese province of Shandong, state media said on Tuesday, though there were no immediate reports of casualties in a country on edge after blasts killed more than 145 people last month.

A single "loud" blast occurred at the plant in Dongying shortly before midnight, state radio said on its official Weibo microblog, showing pictures of the explosion in what appeared to be a fairly remote industrial area.

There were no other details available and Reuters was not immediately able to reach officials for comment.
