The death of Iran's President isn't expected to have immediate impacts internationally. 

President Ebrahim Raisi and the foreign minister have been confirmed dead by state media after a helicopter crash near the Azerbaijan border. 

Iran has announced five days of public mourning. 

Otago University international relations professor Robert Patman told Mike Hosking reaction will come down to whether the crash is deemed an accident. 

He says there will be serious international ramifications if foul play is found to be involved.
