President Trump and Iran declared they've reached an agreement intended to end more than three months of war in Iran and reopen the Strait of Hormuz.

The deal, scheduled to be formally signed Friday in Switzerland, marks a major breakthrough in the conflict that set the Middle East aflame and shook the global economy.

"The Deal with the Islamic Republic of Iran is now complete. Congratulations to all!" Trump wrote on social media on Sunday evening.

Iran's Supreme National Security Council said the deal was reached "following a difficult and intensive period of negotiations lasting several months."

If the agreement works as planned, several key developments are supposed to happen almost immediately.

The U.S. and Iran will end the sporadic attacks that have been taking place despite a ceasefire. The Israel-Hezbollah fighting in Lebanon should stop. And Iran and the U.S. will lift their dueling blockades of the Strait of Hormuz that has prevented oil from leaving the Gulf, driving up prices across the world.

"Ships of the World, start your engines. Let the oil flow!" Trump said in his post.
