The reported move came just hours before Trump’s self-imposed deadline for Tehran to agree to reopen the strategically vital shipping route, the Strait of Hormuz.

Diplomatic engagement between the US and Iran appears to be at a critical juncture after Iranian media reported that Tehran has suspended all formal and indirect communication with Washington, just hours before a deadline set by Donald Trump over the reopening of the Strait of Hormuz.

According to a report by Tehran Times, Iran has shut down every diplomatic and backchannel line of contact with the US.

“Iran has closed all diplomatic and indirect channels of communication with the United States. Any and all message exchanges have also been suspended," the outlet reported on Tuesday.

The reported move came just hours before Trump’s self-imposed deadline for Tehran to agree to reopen the strategically vital shipping route, a demand that has heightened already severe tensions in the region.

However, there are conflicting signals on the status of diplomacy. Sources cited by Reuters said efforts to facilitate talks between the two countries were still ongoing, suggesting that communication may not be entirely severed.
