(CNN) -- The death toll from the May 22 tornado that struck Joplin, Missouri, has risen to 141, city officials announced Sunday.
"Three additional people passed away recently due to injuries sustained during the tornado," the city announced in a statement on its Web site, adding, "It is with deep regret that we make this report."
The Joplin storm was the deadliest single twister in more than 60 years, according to National Weather Service records. The tornado left a 13-mile-long trail of destruction through the southwest Missouri city, stripping the bark from trees and smashing homes into unrecognizable rubble.
Nearly 7,800 households have filed for federal disaster aid in the aftermath, the city reported.
