The head of International Atomic Energy Agency (IAEA) will travel to Tehran this weekend for talks, said the agency on Saturday.

Director General Rafael Mariano Grossi's visit would be his first since President Ebrahim Raisi assumed office in Iran in August. 

"Director General Rafael Mariano Grossi will meet with vice-president of the Islamic Republic of Iran and head of the AEOI, Mohammad Eslami, in Tehran on Sunday," the agency said in a statement, adding that Grossi was expected to hold a news conference upon his return at Vienna airport at around 8:30 p.m.

Kazem Gharibabadi, Iran's ambassador and permanent representative to the Vienna-based international organizations confirmed the visit on social media.
