In an interview with Reuters, the diplomat said that Iran "desperately" needs an easing of sanctions from the United States and that this will be the main calculation in decision-making.

“They understand that they have to start some kind of negotiations after January 20 if they want to ease the sanctions.

They need to keep in mind that they should not take any action before January 20 that would make easing sanctions difficult to achieve, ”Abrams said.

On November 27, Iran attacked Fakhrizada, who was in charge of a research center under the Ministry of Defense.

As a result of the incident, he died.

As the Ambassador of Iran to Russia Kazem Jalali said, the terrorist attack was carried out with the help of foreign special services, and after the explosion of an electrical substation in the area where the murder took place, all video cameras on the route to the house of the deceased scientist were de-energized.

Tehran called the assassination of Fakhrizadeh a gross violation of international norms and said that there was a trace of Israel in it.

Iran has promised to respond to the attack.
