The United Nations Security Council has condemned the suicide bombing attacks which killed nearly sixty people, six of them commanders in the Iranian Revolutionary Guards.

UNSC has underlined the need to bring perpetrators, organizers, financiers, and sponsors of this reprehensible act of terrorism to justice.

The unanimously approved statement came in response to a letter from Iran’s U.N. ambassador, Mohammad Khazaee, who demanded that the 15-nation council take a stand on the bombing, which the Revolutionary Guards chief said was carried out by a group linked to the United States and Britain.

The statement was read out to reporters by Vietnamese Ambassador Le Luong Minh, currently president of the council.

Iran returned to nuclear talks with world powers after furious diplomacy to salvage the negotiations on a uranium enrichment deal which had come to a standstill.

Iranian, US, Russian and French officials resumed their talks at the headquarters of the International Atomic Energy Agency in Vienna late on Wednesday after the American and Iranian sides met separately under the auspices of the IAEA.

The talks, which started on Monday had appeared on the verge of collapse earlier on Tuesday when the Iranian delegation left the building without any explanation and after Tehran said it did not want Paris to be part of a deal.
