"The head of the transitional government, Ali Zeidan, was taken to an unknown destination for unknown reasons by a group" of men believed to be former rebels, the government said in a brief statement on its website.
Zeidan's office initially called the abduction a "rumor" on its official Facebook page. Then it posted a note that said it was "coerced by kidnappers to deny the report", according to CNN.
