LONDON (IRIB) -- Iran has officially complained to BBC over a World Service report that falsely claimed Tehran was happy about North Korea's recent nuclear test.

The Iranian Embassy here said it wanted to "register its strong protest and indeed regret" over the report by the BBC office in Tehran commenting on Iran's stance regarding the recent test.

The claim is "absolutely biased and misleading," the embassy said in a letter to BBC World Service Director Nigel Chapman.

"The Islamic Republic of Iran has frequently declared its opposition to nuclear weapons and related activities," it emphasized.

"Iran has repeatedly called for comprehensive nuclear disarmament under the auspices of the International Atomic Energy Agency (IAEA), while stressing on the inalienable rights of all signatory states of the Non-Proliferation Treaty to benefit from civilian technologies," it said.

The embassy also reiterated that Iran profoundly believes in refraining from any nuclear test by all without exception and considers the ambitions by some states to be a "real jeopardy to regional as well as global security and stability."

The embassy said any reported "happiness on the part of Iran is utterly baseless and the report in no way represents fair and balanced journalism," it added. Reporting from Tehran, BBC claimed that there was "considerable excitement" in Iran over the North Korean achievement and that the tone of Iran television coverage was "clearly congratulatory."

The letter called on the BBC to issue a refutation of the report with similar prominent coverage.
