Iran has sent another chilling threat to Donald Trump as fears of a fresh conflict soar. Iranian Armed Forces Khatam al-Anbiya Headquarters commander Ali Abdollahi Aliabadi said the country is ready to "give a decisive response" to any US "breach of promise".

According to the Fars news agency, he said Iran would not allow the "deceitful and delusional" US President "to misuse or falsely narrate the situation" amid the two-week ceasefire, which is due to end on Wednesday. Aliabadi also warned that Tehran would respond "decisively, conclusively, and immediately" to any threats or breach of the ceasefire from the US.

He said: "The heroic nation of Iran today takes pride in the power, readiness, and comprehensive strategic capabilities of the Revolutionary Guard Corps and other forces of the defenders of the homeland, which have driven the Zionist enemy and the terrorist America to desperation and exhaustion with their lethal and devastating missile and drone strikes, forcing them to humbly request a ceasefire.

"The people of Iran, with their enthusiastic and widespread presence in the squares and streets, have not wavered in their support for the armed forces.

"The brave armed forces of Iran, together with the government and the honorable, amazing nation of Iran, are united and fully prepared to respond decisively, conclusively, and immediately to the enemy's threats and actions, in complete obedience to the directives of the Supreme Commander of the Armed Forces.

"The Armed Forces, with the upper hand, will not allow the deceitful and delusional President of the United States to misuse or falsely narrate the situation on the ground amid the lull in military hostilities, particularly regarding the management and control of the Strait of Hormuz, and will competently respond to any breach of agreement."

This comes after Mr Trump extended the ceasefire deadline by one day as the progress of follow-up negotiations in Pakistan remains uncertain.

Washington and Tehran agreed to a two-week ceasefire on the evening of April 7, which would have required the warring nations to reach a deal by Tuesday, April 21.

However, the President granted negotiators an additional day to secure an agreement, as Iranian officials have yet to formally commit to sending a delegation to Islamabad.

Following the announcement of the extension, he cautioned Iran that it is "highly unlikely that I'd extend it" again, having repeatedly shifted his position on prolonging the ceasefire.

"I'm not going to be rushed into making a bad deal. We've got all the time in the world," Trump told Bloomberg over the phone Monday, adding that he expects fighting to resume if the peace talks fail. "If there's no deal, I would certainly expect."
