Iran says the crises in the Middle East region are largely due to the "colonial" policies of the UK and its allies.

Axar.az reports that Iranian Foreign Ministry Spokesman Bahram Qassemi made the comments on Wednesday in response to remarks made by British Prime Minister Theresa May during a trip to Saudi Arabia.

During an interview with al-Riyadh newspaper, May claimed that Iran was creating tensions and insecurity in the region by interfering in the affairs of Arab nations.

While noting that this was not the first time May had made such baseless claims, Qassemi stressed that Iran’s regional policies are undoubtedly aimed at establishing stability and battling terrorism in the region.

"It is know to all that Iran has played a significant role in supporting security, stability and peace in the countries that have been attacked by terrorists and have requested aid from the Islamic Republic," he said.
