The American newspaper "Wall Street Journal" reported on Friday that Iranian authorities have provided the American side with documents assuring they will not attempt to assassinate Donald Trump. The papers sent to President Joe Biden's administration in October did not contain signatures of any officials.

One problem area coming into focus is Parchin, where experiments on an A-bomb were under way until Israel attacked it last month.

Israel's airstrikes on Iran last month destroyed a top-secret Iranian nuclear research facility at Parchin, according to reports.

The Israeli strike on Iran's Parchin military complex in late October will make it much harder for Iran to develop a nuclear explosive device if it chooses to do so, two Israeli officials told Axios.
