Iran's state TV says Ghazanfar Roknabadi, a former ambassador to Lebanon, is among those missing after at least 719 pilgrims died in a stampede during the hajj pilgrimage in Saudi Arabia.

The Saturday broadcast said two Iranian state TV reporters and a prominent political analyst are also missing. At least 134 Iranian pilgrims died and 85 were injured in the Thursday incident, while 354 Iranian pilgrims remain missing, according to the report.

Iran has strongly criticized archrival Saudi Arabia over the disaster, blaming the Saudi government for "incompetence" and "mismanagement" of the annual hajj.
