"They should explain why they attacked us in the middle of … negotiations, and they have to ensure that they are not going to repeat that [during future talks]," Araghchi said. "And they have to compensate [Iran for] the damage that they have done."

The Iranian diplomat didn't specify what sort of compensation Iran was seeking, but the US does have the ability to release billions in frozen Iranian funds.

It's unlikely that the Trump administration would go for anything like that since it has been imposing fresh sanctions on Iran, continuing the so-called "maximum pressure" campaign.

Araghchi said that "anti-negotiation feelings" were very high within Iran since Israel launched the war under the cover of previous US-Iran talks.
