Iran’s state-affiliated news outlet Tasnim said on Monday that Iranian negotiators would stop exchanging messages with the US through intermediaries and that Tehran would take steps to completely close the Strait of Hormuz in retaliation for ongoing ceasefire violations.
The report, in a translated post on social media site Telegram, focuses on Israel’s military operations in Lebanon against the Iran-backed militia Hezbollah.
Oil prices rose more than 5% after Tasnim’s report, which signaled a failure in efforts to reach a diplomatic end to the war now in its fourth month.
Just three days earlier, President Donald Trump had said he would decide at a meeting in the White House Situation Room whether to agree to a deal with Iran that would at least prevent conflict. But that meeting ended without Trump taking a final decision.
The White House and US Central Command did not immediately respond to CNBC’s requests for comment on the report.
