DUBAI/WASHINGTON, June 15 (Reuters) - Pakistani Prime Minister Shehbaz Sharif said late Sunday (Monday local time) that the United States and Iran had reached an agreement to end their war, adding that the formal signing ceremony would take place on Friday in Switzerland.

Trump wrote in a post on his Truth Social platform shortly after Sharif's announcement, "The agreement with the Islamic Republic of Iran is now complete."

The agreement was reached despite Israeli attacks on Lebanon on Sunday, which drew criticism from Iran and Trump.

The exact terms of the agreement are not yet known. Sharif said the agreement calls for "an immediate and permanent cessation of military operations on all fronts, including Lebanon."

Multiple sources had previously told Reuters that the draft agreement would lead to the reopening of the Strait of Hormuz, the end of the US blockade on Iranian ports, and an extension of the ceasefire, while postponing discussions on Iran's nuclear program during a 60-day period of talks.

In his social media post, Trump said the strait would be open "without paying transit fees" and that the US naval blockade would also end.

He added, "Ships of the world, start your engines. Let the oil flow!"
