DOHA (AFP) - Qatar's foreign minister on Thursday (June 8) rejected interference in his country's foreign policy, ruling out a military solution to a crisis which has seen Riyadh and its allies cut ties with Doha.

"No one has the right to intervene in our foreign policy," Sheikh Mohammed bin Abdulrahman Al-Thani told AFP.

"We don't see a military solution as an option" to the crisis, he added.

A top United Arab Emirates official on Wednesday (June 7) told AFP that the unprecedented measures against Qatar aim to pressure Doha into making drastic policy changes.

"This is not about regime change - this is about change of policy, change of approach," state minister for foreign affairs Anwar Gargash said, accusing the government in Doha of being in "denial".

Saudi Arabia, the UAE, Egypt and Bahrain lead a string of countries that cut ties with Qatar this week over what they say is the emirate's financing of extremist groups and its ties to Iran, Saudi Arabia's regional arch-rival.

Qatar denies having any ties to extremists.

The UAE's Gargash on Wednesday told AFP the measures against Doha were limited to diplomatic and economic ties, but warned that no one could project the "dynamic of a crisis".

"Like any crisis, you cannot really control the dynamic... this is one of the dangers of any crisis. There is no intention for us to seek anything but what we look at as economic spheres of activities," he said.

The four Arab countries have suspended all flights to and from Doha and closed off sea and air links to Qatar.

Saudi Arabia has also closed off Qatar's only land border, a crucial lifeline for food imports.

Sheikh Mohammed said Qatar could nonetheless survive "forever", adding that it respected international agreements and would continue supplying liquefied natural gas to the UAE.

Qatar is the world's largest exporter of natural liquefied gas.

The emirate is also home to leaders of Egypt's Muslim Brotherhood, the Palestinian Hamas and the Afghan Taliban.

Analysts say the crisis is in part an extension of a pre-existing dispute which saw Saudi Arabia, the UAE and Bahrain temporarily recall their ambassadors from Doha in 2014 over Qatari support for the Muslim Brotherhood.
