Tehran (Web Desk): Iran's Foreign Ministry has urged the Arab nations to negotiate to end Qatar crisis, local media reported.

“These countries who have cut ties to Qatar should try to settle their differences at the negotiating table in a positive and comprehensive process," Ministry Spokesman Bahram Ghasemi told reporters in a weekly news conference.

The diplomatic crisis, the worst since the 1990 invasion of Kuwait by Iraq and the subsequent Gulf War, has seen Arab nations and others cut ties to Qatar, which hosts a major US military base and will be the host of the 2022 FIFA World Cup.

Ghasemi also says of the countries involved: “They should move toward peace and stability in the region and we invite them to negotiating and exercising restraint.”

Qatar's neighbours cut ties with the country over accusations that it sponsors Islamic extremism, which Qatar denies. France has economic and military ties with Qatar and other Gulf states.

Qatar says it has begun shipping cargo through to Oman to bypass Gulf countries that have cut off sea routes to the tiny, energy rich nation.
