Iran on Thursday claimed Saudi airstrikes in Yemen had hit its embassy in Sanaa on Wednesday. Iran also placed a ban on all products from Saudi Arabia on Thursday. 

Iran accused Saudi warplanes of targeting its embassy in the Yemeni capital of Sanaa with a rocket, the country's state media reported, in a fresh escalation of diplomatic tensions between the two countries.

Tehran called the incident 'intentional', and said that the embassy guards had been injured in the strike and the building's wall was damaged by the rocket's shrapnel.

'The intentional act of the Saudi government was a violation of all international conventions and regulations about protecting the security and safety of diplomatic missions in all situations," Foreign Ministry Spokesman Hossein Jaber-Ansari said, according to the Islamic Republic News Agency

The Saudi-led coalition that has been conducting airstrikes in Yemen since last year is reportedly investigating Tehran's claims. 

The Yemen crisis has been largely seen as a proxy war between Sunni Saudi Arabia and Shiite Iran, with Riyadh accusing Tehran of backing Houthi rebels who have been trying to wrest control in Sanaa.

Tensions between the two Middle Eastern nations escalated after Saudi Arabia executed Shia cleric Sheikh Nimr al-Nimr last week, leading to protests in Iran and the Saudi embassy in Tehran being attacked.

Saudi Arabia cut off diplomatic ties with Iran following the embassy attack and cancelled flights and cut off trade ties with the country. 

Several countries, including Russia, Pakistan and Iraq have offered to mediate to restore ties between Iran and Saudi Arabia. 

Iraqi Foreign Minister Ibrahim al-Jaafari arrived in Tehran on Wednesday with an offer for mediation, Reuters reported. 

Pakistan is also set to raise the issue when Saudi Foreign Minister Adel al-Jubeir visits Islamabad on Thursday, according to Bloomberg
