President Donald Trump said Monday that he had delayed a planned attack on Iran at the request of the Gulf States, citing what he called "serious negotiations."

The U.S. and Israel have been at war with Iran since Feb. 28. While the U.S. and Iran are under a weeks-long ceasefire, the sides cannot agree to a peace agreement, with Iran's pursuit of a nuclear weapon a major sticking point. 

"I have been asked by the Emir of Qatar, Tamim bin Hamad Al Thani, the Crown Prince of Saudi Arabia, Mohammed bin Salman Al Saud, and the President of the United Arab Emirates, Mohamed bin Zayed Al Nahyan, to hold off on our planned Military attack of the Islamic Republic of Iran, which was scheduled for tomorrow, in that serious negotiations are now taking place, and that, in their opinion, as Great Leaders and Allies, a Deal will be made, which will be very acceptable to the United States of America, as well as all Countries in the Middle East, and beyond," Trump posted on Truth Social.

Trump previously backed off a threat to destroy Iranian civil infrastructure due to the advent of the ceasefire, brokered by Pakistan. 

Trump has repeatedly fumed over Iran's peace-negotiation tactics, asserting that divisions within the Tehran government had made it nearly impossible to reach an agreement with the country.
