Iran has reportedly agreed to provide access to the UN for the inspection of Iranian military sites.

Iran reached a comprehensive nuclear deal with the world powers P5+1 countries in Vienna on Tuesday.

The deal struck with Britain, China, France, Germany, Russia and the US, includes an Iranian agreement to provide access to the UN for the inspection of Iranian military sites.

Iran had repeatedly refused to give international inspectors access to its military sites, stating that such access would be a violation of its sovereignty, as well as its state and military secrets.

However, Iran will have the right to challenge the UN’s request, according to a Western diplomatic source.

In late May, Supreme Leader of Iran Ayatollah Ali Khamenei, Iranian President Rouhani and Foreign Minister Javad Zarif declared the issue a “red line” during the nuclear negotiations.

The sides are expected to make a joint statement, disclosing the details of the agreement, at a press conference scheduled for Tuesday at around 12 p.m. local time in Vienna (1100GMT)./AA/
