A delegation from the International Atomic Energy Agency arrived in Iran on Monday for technical talks with Iranian officials, ahead of the fourth round of indirect negotiations between Iran and the United States over Tehran’s nuclear program on Saturday.

The visit comes as Iran declared a day of mourning Monday following an explosion at country's largest commercial port over the weekend that killed at least 46 people and injured over 1200, Iranian outlets reported. 

Two days after the massive explosion, Agence France-Presse reported that firefighters were still battling large fires at Shahid Rajaee Port in Iran's south near the strategic Strait of Hormuz on Monday while authorities remained tightlipped about the cause of the incident.

According to the Washington Post, Israel launched a cyberattack targeting the Shahid Rajaee Port in 2020.
