The United States has signaled that military action against Iran remains an option as negotiations over a potential peace and nuclear agreement continue without a final breakthrough.

The warning comes amid ongoing diplomatic efforts to end tensions that have disrupted regional stability and raised concerns about global energy markets.

Senior US officials indicated on Saturday that Washington retains the capability to resume military operations against Iran if negotiations fail to produce an acceptable agreement.

The comments followed a White House Situation Room meeting chaired by President Donald Trump, who is reportedly reviewing proposals related to a possible deal with Tehran.

Speaking at a major defense forum in Singapore, US Defense Secretary Pete Hegseth said the United States remained prepared for further action if necessary.

According to Hegseth, US military resources and weapons stockpiles remain capable of supporting renewed operations both in the Middle East and elsewhere if circumstances require.

The latest developments come as diplomatic efforts continue through international mediation channels aimed at reducing tensions and establishing conditions for a broader agreement.

"President Trump will only make a deal that is good for America and satisfies his red lines," a White House official said following Friday's high-level meeting.

The official reiterated that one of Washington's primary conditions remains preventing Iran from obtaining a nuclear weapon.

Iranian officials, however, rejected what they described as demands imposed by Washington.

Foreign Ministry spokesman Esmaeil Baqaei said Tehran would not accept negotiations based on ultimatums, adding that discussions were continuing but that no final agreement had been reached.

Negotiations between the United States and Iran have intensified in recent weeks following military exchanges that heightened tensions across the Middle East.

The Strait of Hormuz, one of the world's most important oil shipping routes, has emerged as a major focus of discussions due to its significance for global energy supplies and international trade.

At the same time, efforts to reduce hostilities in Lebanon remain linked to wider regional diplomacy, with Israeli and Lebanese representatives continuing talks through military and diplomatic channels.

While diplomatic contacts remain active, significant differences continue to separate Washington and Tehran on key issues, including nuclear restrictions and economic conditions. The situation remains fluid as both sides continue negotiations and regional tensions persist.
