Joplin, Mo., slammed by twister; at least 89 dead

Death toll expected to rise after massive tornado tears through southwest Missouri; "It cut the city in half," official says

JOPLIN, Mo. (CBS/AP) - A massive tornado that tore a 6-mile path across southwestern Missouri killed at least 89 people as it slammed into the city of Joplin, ripping into a hospital, crushing cars like soda cans and leaving a forest of splintered tree trunks behind where entire neighborhoods once stood.

Authorities warned that the death toll could climb as search and rescuers continued their work Monday. A thunderstorm lashed the city in the morning, hampering search and rescue efforts.
