IRNA � The 8th report of UN nuclear watchdog on Iran's commitment to its obligations, which is due to be published in coming days, is a fresh touchstone for the body's impartiality, as it has recently been facing rising pressures from the US.

The US ambassador to the UN Nikki Haley visited the International Atomic Energy Agency (IAEA) Director General Yukiya Amano last Week as part of what the US President Donald Trump calls reviewing the nuclear agreement with Iran.

Iran and the major world powers-the US and the UN Security Council permanent members plus Germany- signed the nuclear deal in 2015 known as Joint Comprehensive Plan of Action (JCPOA).

Although Trump administration as well as the International Atomic Energy Agency (IAEA) have repeatedly confirmed Iran's commitment to the JCPOA, some US media have reported that Trump and his team are trying to show that Iran is not complying with the agreement.

Haley in her visit with head of the IAEA pressed the global watchdog to seek access to Iran's military bases to ensure Iran is committed to its obligations.

Under the agreement Iran accepted to curb its nuclear program in return of sanctions relief, but inspecting the country's military sites is not among the contents of the deal.

The visit was followed by Iran's explicit protests. Foreign Minister Mohammad Javad Zarif wrote a letter to Amano to say that the visit 'raises several serious concerns over further violations of the letter and spirit' of the nuclear agreement and the UN Security Council rsolution 2231 that supports it.

Warning on the destructive consequences of any illegitimate pressure on IAEA, Iran's mission at the nuclear watchdog in Vienna, echoed Foreign Minister's remarks in a statement.

The meeting is in conflict to various articles of the nuclear deal, as well as contradicting the resolution 2231 of the UN Security Council on the agency's role and the necessity of maintaining its independence and protecting the sensitive information which is submitted to the IAEA, the statement read.

The statement also emphasized that all the parties to the agreements should remain committed to their obligations.

The statement argues that Iran is familiar with and will remain committed to its obligations and responsibilities under Safeguards Agreement, Non-proliferation Treaty (NPT), the Additional Protocol and JCPOA.

It has also stressed that Iran would not let the content of the documents be exploited or politicized by a specific state.

Given all the overt and covert pressures by the US on the Agency to obtain access to Iran's military sites, the report would be of a significant sensitivity.

Iranian officials, including Foreign Ministry's spokesman Bahram Qasemi, have asserted that there would be no access to the sites regarded as forbidden in the negotiations.

The upcoming report on Iran's nuclear activities and commitment to the international agreements, which is likely to be published on Thursday, would illustrate IAEA's impartiality and independence, particularly in face of such pressures and illegitimate demands.
