Essam Baitelmel, a member of the Libyan team investigating the abduction, said the kidnappers had demanded the release of Mohamed Dersi, a Libyan Islamist militant jailed for life in 2007 for plotting to blow up the main airport in Jordan.
The kidnappers made their demands in a call to the ambassador's own cellphone, which was left behind in the car after the abduction, Baitelmel said. They said the diplomat was unharmed.
Jordanian Prime Minister Abdullah Ensour told parliament the government would take "all necessary measures to protect his life and release him."
"Jordan has currently locked up some of the top global al Qaeda scholars and jihadists like Mohammad al Makdisi and Abu Qatada. A deal over Dersi may encourage other jihadists to follow suit, so, very tricky," a senior Jordanian intelligence official told Reuters.
