Vice President JD Vance on Monday did not rule out a role for US troops in enforcing a nuclear agreement with Iran, although he said he did not expect that "US military forces are going to be necessary."
Speaking to CBS, Vance said the United States would be present to ensure that Iran's stockpiles of highly enriched uranium were destroyed.
The United States had already discussed with Tehran how the enriched uranium could be eliminated, he said.
Washington intends to work with both the International Atomic Energy Agency (IAEA) and Iran on the process, Vance added. He said it remained unclear what role the United States would ultimately play.
"Whether we play an observer role or whether we play a more active role, these are the sorts of things that we'll figure out in technical talks," Vance said.
He also rejected reports that Tehran would receive $24 billion in frozen assets if it met certain conditions under the agreement.
The figure "doesn't appear anywhere in any of the texts that we've talked about with the Iranians," Vance said.
The United States and Iran agreed on Sunday to a framework accord to end the war, although few details of the peace deal have been made public.
Many analysts view the agreement as a stepping stone rather than a final settlement, with major challenges remaining, from Iran's nuclear programme to tensions surrounding Israel's military campaign in Lebanon.
