UN Secretary-General Antonio Guterres on Thursday joined global calls to resolve tensions between Qatar and other Gulf Arab states, and said he was ready to support any diplomatic efforts "if desired by all parties".
The comment come just days after the UAE, Saudi Arabia and several other MENA region countries cut all diplomatic and trade ties with Qatar over its alleged support for terrorist groups.
"The aim as I see it is to straighten an evil that has targeted the region", Anwar Gargash, United Arab Emirates minister of state for foreign affairs, tweeted.
Under-fire Qatar - which is due to host the football World Cup in 2022 - vehemently denies the accusations.
Bloomberg cited International Energy Agency data as confirming the emirates relies on gas to meet half of its electricity needs and would need to replace Qatari fuel with more expensive liquefied natural gas if the Dolphin Energy pipeline were to close.
Turkey is a key ally of Qatar and is setting up a military base in the country which also hosts the largest US air base in the Middle East. Iran shares access with Qatar to the world's biggest natural gas field.
"Qataris are questioning whether this is going to end up in seeing a change in leadership itself in Qatar", he said.
Saudi Arabia has also closed its land borders with Qatar, geographically isolating the tiny Gulf state. He offered no documents to support his claim, but Western officials long have accused Qatar's government of allowing or even encouraging funding of Sunni extremists.
On Tuesday, Saudi Foreign Minister Adel al-Jubeir called on Qatar to cut ties with Palestinian Islamist group Hamas in the occupied territories, and the Muslim Brotherhood in Egypt, if it wanted to end its isolation.
The Gulf countries have ordered their citizens out of Qatar and given Qataris overseas 14 days to return home.
Qatar-based broadcaster Al-Jazeera said that it was under a wide-scale cyberattack, which had targeted "all systems", according to a statement released on social media by the broadcaster. This is a significant matter since "Qatar doesn't have that many vessels and most of their exports are co-loaded with other crudes", an another shipbroker said".
He added: "Doha now is completely isolated".
"The decisions that were made were very strong and will have a fairly large cost on Qatar and we do not believe that Qataris want to sustain those costs". FBI agents are assisting Qatar in its investigation, said Meshal bin Hamad Al Thani, Qatar's ambassador to the U.S.
"This is not about regime change - this is about change of policy, change of approach", Gargash said.
