Devastation in tornado-hit US city of Joplin, Missouri

The US state of Missouri has released a list of more than 230 people missing since a devastating tornado struck the city of Joplin on Sunday.

But the list is shrinking as people are located, and officials hope others have simply failed to contact relatives.

The tornado killed at least 125 people, injured 750 and wrecked as much as a third of the city, making it one of the most destructive in US history.
