World leaders reached a framework Thursday for a final deal on the future of the Iranian nuclear program.
At marathon talks in Switzerland, Secretary of State John Kerry, German diplomats and leaders from Iran all said that a framework had been reached. They were quickly followed by an announcement from a European official at the talks.
"Back to work soon on a final deal," Kerry said on Twitter. He called it a "big day."
Javad Zarif, the foreign minister of Iran, said on Twitter: "Found solutions. Ready to start drafting immediately."
President Barack Obama planned to deliver a statement at 2:15 p.m. ET from the White House Rose Garden.
Iran and six world powers, including the United States, have been in negotiations since March 26 on the nuclear program, which Iran insists is peaceful. The six nations want limits on the program, and Iran wants the lifting of punishing economic sanctions.
The countries had set a deadline of Tuesday for a framework, but they blew past it and kept talking. They worked through the night into Thursday, taking a break of just a few hours for sleep.
