US Secretary of State Antony Blinken says seven Americans are now free from detention or imprisonment in Iran and on their way back home.

"Five of the seven of course had been unjustly detained, imprisoned in Iran, some for years," said Blinken in New York on Monday.
"Two others had been prevented from leaving Iran."
The five prisoners sought by the U.S. in a swap with Iran were freed and left Tehran on Monday as part of a deal that saw nearly $6 billion in Iranian assets unfrozen.
Despite the deal, tensions are almost certain to remain high between the U.S. and Iran, which are locked in various disputes, including over Tehran's nuclear program. Iran says the program is peaceful, but it now enriches uranium closer than ever to weapons-grade levels.
The planned exchange has unfolded amid a major American military buildup in the Persian Gulf. And comes ahead of the convening of world leaders at the U.N. General Assembly this week in New York, where Iran's hard-line President Ebrahim Raisi will speak.
