Back home from New York, President Hassan Rouhani says Washington's attempts to advance an anti-Iran agenda at the UN only backfired, stressing that this year's General Assembly session and related events further exposed the US's isolation on the world stage.

Speaking at Tehran's Mehrabad airport on Thursday, President Rouhani briefed the reporters on the outcome of his trip to New York, where he attended the 73rd session of the UN General Assembly, met with world leaders on the sidelines, and gave several interviews to American media outlets.

The Iranian president touched on the administration of US President Donald Trump's abortive attempts to put pressure on Iran and show it as an isolated country at the world body.

Trump had "no achievement," neither in his speech to the General Assembly, nor at the Iran-centered UN Security Council meeting he chaired a day later, Rouhani added.

At the General Assembly, Rouhani said, Trump was laughed at when he began to speak in praise of his administration's performance, adding that global media took that laughter as "humiliating for the American government and nation."

Rouhani said the US sought to use its capacity as chair of the UN Security Council to single out Iran at the meeting, which was held on the sidelines of the General Assembly's session, only to face the "reverse effect."

That meeting turned, instead, into a strong show of support for the 2015 multilateral nuclear deal with Iran , which the Trump administration scrapped in May in defiance of the very same council's Resolution 2231, said Rouhani.
