President Donald Trump's son-in-law Jared Kushner and U.S. special envoy Steve Witkoff met Tuesday in Switzerland with Iranian officials for nuclear talks, according to a report.

Kushner and Witkoff previously met with Iranian delegates in Muscat, Oman, on Feb. 6.  

Iranian Deputy Foreign Minister Majid Takht-Ravanchi said his country is willing to reach a nuclear deal if the U.S. agrees to ease some or all of its sweeping sanctions, including restrictions on Iran’s oil exports, banking system, and access to the global financial network.

“We cannot accept the notion that Iran has to do certain things without the other side committing itself to do their share. It has to be give and take; that’s what compromise is all about.”

Trump has called for regime change in Iran, and both he and the Iranian supreme leader, Ayatollah Ali Khamenei, have threatened each other with military action. The Defense Department sent a second aircraft carrier, the Gerald R. Ford, to the Middle East to join the USS Abraham Lincoln and other U.S. military assets.

“In case we don’t make a deal, we’ll need it,” Trump said Friday.

Iran has warned that, if threatened, it will target U.S. military bases in the region.
