American Jeffery Woodke, who was held hostage in Niger since October 2016 has been released.

An American missionary who was kidnapped in Niger has been released, U.S. officials said Monday.

Jeffery Woodke, a Christian humanitarian aid worker, was released after more than six years in captivity, the White House said.

"I’m gratified & relieved to see the release of U.S. hostage Jeff Woodke after over 6 years in captivity," U.S. national security adviser Jake Sullivan tweeted. "The U.S. thanks Niger for its help in bringing him home to all who miss & love him. I thank so many across our government who’ve worked tirelessly toward securing his freedom."
