Iran's foreign minister has complained to the United Nations about Saudi Arabia's policies after a diplomatic crisis broke out between the countries following an attack on the Saudi embassy in Tehran.
Iranian news agencies on Saturday published a letter sent to UN Secretary-General Ban Ki-moon and Iran's foreign minister, Mohammad Javad Zarif, said in the letter "some people" in Saudi Arabia appeared to wish to push the whole region into crisis.
Saudi Arabia cut diplomatic ties with Iran after Iranian protesters overran and set fire to the Saudi Embassy in Tehran and the consulate in Mashhad last Sunday.
Afterwards, Bahrain and Sudan cut diplomatic ties with Iran and the United Arab Emirates downgraded its relations with the country on January 4.
Iranian Foreign Minister Zarif said Iran had "no desire" to increase tensions.
Zarif accused Saudi Arabia of engaging in a series of "direct provocations" against Iran, including the execution of Shiite cleric Nimr al-Nimr.
Zarif also described Saudi Arabia in the letter as a threat to regional and global security.
Saudi Arabia stated that the incident was a Saudi internal matter and that Iran is the country instigating sectarian division by portraying itself as the leader of Arab Shiites.
The Saudi government on January 2 executed Nimr al Nimr and 46 others, mostly suspected Al Qaeda members, after they were convicted of terror-related offences.
Nimr and three other Shiites were accused of killing several policemen and organising petrol bomb attacks that killed several police officers during anti-government protests between 2011 and 2013.
