US President Donald Trump announced that the temporary US-Iran ceasefire will be extended until Iranian officials submit a “unified proposal” for discussion in a post on Truth Social on Tuesday.
The decision to extend the ceasefire, which was set to expire on Wednesday, was made “based on the fact that the Government of Iran is seriously fractured” and upon the request of Pakistani officials, Trump stated.
In addition to the ceasefire extension, the US blockade on the Strait of Hormuz will also continue, he clarified.
An advisor to Iranian Parliament Speaker Mohammad-Bagher Ghalibaf decried the ceasefire extension as "a ploy to buy time for a surprise strike" that "means nothing" in a post on X/Twitter.
"The continuation of the siege is no different from bombardment and must be met with a military response," he asserted, urging Iran to "take initiative" in response to the announcement.
US, Iranian delegations not to attend second round of negotiations
Earlier on Tuesday, Iranian semi-official Islamic Revolutionary Guard Corps-tied outlet, Tasnim, reported that Iranian officials had decided not to attend the second round of talks in Pakistan.
A senior Iranian official also told Reuters that Iran may consider attending talks if "Washington abandons its policy of pressure and threats," adding that Tehran rejects negotiations aimed at surrender.
The official accused Washington of "creating new obstacles every day instead of resolving the differences" to end the war and stated that Pakistan was continuing efforts to persuade the United States to lift its naval blockade on the Strait of Hormuz.
The Jerusalem Post also learned that US Vice President JD Vance's trip to Pakistan for the talks had been canceled.
US Ambassador to Israel Mike Huckabee has been called to return to Washington in order to participate in discussions on the developing situation with Iran, N12 also reported on Tuesday.
Iran ready for military response
Iran's armed forces are ready to deliver an "immediate and decisive response" to any renewed hostile action by its adversaries, a senior Iranian military commander also said on Tuesday, according to semi-official Tasnim news agency.
Ghalibaf said that Iran would not accept negotiations beneath the shadow of threats, and is prepared to reveal new cards on the battlefield in a post on his X/Twitter account.
