Jordanians now support the military campaign against the self-declared Islamic State. But King Abdullah still faces domestic opponents, religious and secular, who chafe at restrictions at home.
A defense official tells NPR that the rebels will be vetted and screened under top-secret protocols. Qatar, Jordan and Saudi Arabia will also be part of the effort.
Repeated airstrikes on the self-described Islamic State are "the beginning of our retaliation" for the extremist group's brutal killing of a captured pilot, Jordan's foreign minister says.
Many Jordanians opposed joining the U.S.-led coalition against ISIS. But at the funeral of the pilot burned to death by the extremists, mourners honored his sacrifice and called for ISIS' destruction.
A video from the self-declared Islamic State militant group shows Jordanian pilot Lt. Muath al-Kaseasbeh, who had been held by the group since his capture in December, being burned alive.
Jordan executed two prisoners in revenge for the horrific killing of the 26-year-old pilot, including the Iraqi woman who was sought by the so-called Islamic State for a hostage exchange.
