Regional rivals Saudi Arabia and Iran sent experts to hold talks on security issues and cooperation, Jordan’s official state news agency reported Monday.

The “security dialogue” took place at the Arab Institute for Security Studies in Amman, the Petra news service said, without identifying any of the representatives from either side.

Discussions were in “an atmosphere of mutual respect,” according to the institute’s secretary general, Ayman Khalil, the report said, and covered issues such as reducing missile threats, ballistic weapons delivery vehicles and technical measures needed to build confidence over Iran’s nuclear program.
