Iran has suspended all exchanges with the US via mediators on Monday, IRGC-affiliated news agency Tasnim reported, as the two sides remained apart on a deal to extend the ceasefire and end the war.

The decision was made over what the news agency said were "continuing crimes" of Israel in Lebanon.

"Considering that Lebanon was one of the preconditions for the ceasefire and that this ceasefire has now been violated on all fronts, including Lebanon, the Iranian negotiating team is suspending dialogues and exchange of texts through mediators," Tasnim reported.

Iranian Foreign Minister Abbas Aragchi said earlier on Monday that a violation on one front of the ceasefire is a violation “on all fronts” and that the US-Iran ceasefire is “unequivocally a ceasefire on all fronts, including in Lebanon”.

“Its violation on one front is a violation of the ceasefire on all fronts. The US and Israel are responsible for the consequences of any violation,” Araghchi wrote on X.
