By Parisa Hafezi DUBAI, Feb 2 (Reuters) - Iran is weighing the terms for resuming talks with the United States soon, a foreign ministry official said on Monday, after both sides signalled readiness to revive diplomacy over a long-running nuclear dispute and dispel fears of a new regional war.

Ahead of the Friday talks scheduled between officials from Washington and Tehran, Iran has demanded a change in the venue and the format of talks. For weeks, US President Donald Trump has been threatening to launch a military strike on Iran over its crackdown on protesters,

Iran is ready to participate in “fair and just” nuclear talks with the United States amid rising tensions between the two nations, but will not be dictated to, Iranian Foreign Minister Abbas Araghchi said Friday.

Iran's supreme leader warned Sunday that any attack by the United States would spark a "regional war" in the Mideast, further escalating tensions as President Donald Trump has threatened to militarily strike the Islamic Republic.

Turkey is attempting to bring U.S. and Iranian officials to the negotiating table in hopes of easing the threat of U.S. military action against Iran. Neither the U.S. nor Iran has confirmed whether they plan to take part in any negotiations.

U.S. allies and partners in the Middle East again are urging restraint from both the United States and Iran as the Trump administration warns of a possible strike and builds up its military presence in the region.

Even with US forces poised to strike Iran, Foreign Minister Abbas Araghchi told CNN that he was “confident that we can achieve a deal” on Tehran’s nuclear program.

If it refuses to make a deal, he said, the next attack would be “far worse” than the raids on Iran’s nuclear sites last year. That is a credible threat. The centrepiece of the armada is the USS Abraham Lincoln,

Iran issued a stern warning as President Donald Trump builds up America's military presence in the Middle East.

U.S. naval and air forces are moving toward the Middle East as tensions with Iran rise, highlighting deterrence efforts, escalation risks, and what the buildup means for servicemembers operating in the region.
