KANSAS CITY (Reuters) - The death toll from last month's devastating tornado in Joplin, Missouri, has risen to 156, the city said on Wednesday.

Grace M. Sanders, the latest victim, died of injuries sustained in the tornado, Lynn Onstot, public information officer for the city, said in a statement.

The tornado, which cut a six-mile swath through Joplin and destroyed 6,000 homes and many other buildings in the city, was the deadliest in the United States in more than 60 years.
