Iranian authorities have launched an investigation into Sunday's helicopter crash that killed President Ebrahim Raisi and his foreign minister.

It's the second of five official days of mourning. Tens of thousands of people have been paying their respects.

Iran has announced early presidential election next month.

Raisi and eight others were killed after their helicopter crashed in a remote, mountainous area near Iran's border with Azerbaijan.
