An outline by the Trump administration would allow Iran to continue enriching uranium at low levels while a broader arrangement is worked out that would block the country’s path to a nuclear weapon.

Iran’s foreign minister said Tuesday that Tehran will respond to a recent US proposal on the Iranian nuclear program “in the coming days.” “The US proposal contains many ambiguities and questions,” Abbas Araghchi said during a book signing event in the Lebanese capital, Beirut.

At an international conference in Tehran, top Iranian officials said they were eager to make a deal with Trump but that they wouldn’t buckle under pressure.
