According to the BBC, Bahrain, Saudi Arabia, the United Arab Emirates, Egypt, Yemen and Libya have all announced their support of the split.
Bahrain's foreign ministry issued a statement saying it would withdraw its diplomatic mission from the Qatari capital, Doha, within 48 hours and that all Qatari diplomats should leave Bahrain within the same period.
Bahrain said its decision was based on what it said was Qatar's destabilizing actions.
Egypt's Minister of Immigration and Egyptian Expatriate Affairs, Nabila Makram Ebeid, affirmed on Monday that Egyptians can return from Doha to Cairo through other available flights from countries that have not cut their ties with Qatar.
Trouble is brewing in the Middle East after six Arab countries led by Saudi Arabia cut diplomatic ties with Qatar, accusing it of destabilising the region.
"To resolve regional disputes and the current dispute, they should adopt peaceful methods, transparent dialogue and diplomacy", foreign ministry spokesman Bahram Qasemi said.
In a statement, Egypt said that Qatar had taken an "anti-Egyptian course" and that Cairo had been unable to dissuade it from supporting terrorism.
It said: "We have no further comments for the time being".
The statement accused Qatar of supporting what it described as Iranian-backed militants in its restive and largely Shi'ite Muslim-populated Eastern region of Qatif and in Bahrain.
Premier UAE airlines Etihad and Emirates announced they would suspend flights to Qatar, as did budget carriers Air Arabia and FlyDubai.
Qatar had assigned warplanes to the coalition conducting air strikes against Yemen's Huthi rebels.
Stocks in Qatar slumped to their lowest in more than a year Monday after five countries severed relations with the Gulf state.
Qatar also says the decision is a "violation of its sovereignty", vowing to its citizens it won't affect them.
"The Qatari Government will take all necessary measures to ensure this and to thwart attempts to influence and harm the Qatari society and economy", it said. However, it remains a key financial patron of the Hamas-controlled Gaza Strip and has been the home of exiled Hamas official Khaled Mashaal since 2012.
Doha has long faced accusations that it is a state sponsor of terror.
Although the Qatari government flatly denied that the comments had been made - insisting that QNA's website had been hacked - the report ignited a powder keg of political tension that had always been brewing in the Gulf.
