Qatar has issued a statement saying there is 'no legitimate justification' for four Arab nations cutting diplomatic ties to it. Qatar also says the decision is a 'violation of its sovereignty,' vowing to its citizens it won’t affect them. 

"The campaign of incitement is based on lies that had reached the level of complete fabrications," the Qatari foreign ministry said.

It added that, as a member of the Gulf Cooperation Council, it was committed to its charter, respected the sovereignty of other states and did not interfere in their affairs.

Qatar’s Foreign Affairs Ministry made the statement Monday, hours after Bahrain, Egypt, Saudi Arabia and the United Arab Emirates announced it would be cutting ties to the peninsular nation.

The dispute between Qatar and the Gulf’s Arab countries started over a purported hack of Qatar’s state-run news agency. It has spiraled since.

Earlier, Saudi Arabia, Egypt, the United Arab Emirates and Bahrain severed their ties with Qatar today, accusing it of supporting terrorism, opening up the worst rift in years among some of the most powerful states in the Arab world.

The coordinated move dramatically escalates a dispute over Qatar's support of the Muslim Brotherhood, the world's oldest Islamist movement, and adds accusations that Doha even backs the agenda of regional arch-rival Iran.

Announcing the closure of transport ties with Qatar, the three Gulf states gave Qatari visitors and residents two weeks to leave their countries. Qatar was also expelled from a Saudi-led coalition fighting in Yemen.

Economic disturbances loomed immediately, as Abu Dhabi's state-owned Etihad Airways said it would suspend all flights to and from Doha from Tuesday morning until further notice.

Oil giant Saudi Arabia accused Qatar of backing militant groups and broadcasting their ideology, in an apparent reference to Qatar's influential state-owned satellite channel al Jazeera.

"(Qatar) embraces multiple terrorist and sectarian groups aimed at disturbing stability in the region, including the Muslim Brotherhood, ISIS (Islamic State) and al-Qaeda, and promotes the message and schemes of these groups through their media constantly," the Saudi state news agency SPA said.

Meanwhile, Foreign Office stated that Pakistan has no immediate plans to cut diplomatic ties with Qatar, a spokesman for the foreign ministry said today.

The country "has no such plans," the spokesman, Nafees Zakaria, said, following today's surprise severing of ties with Qatar by Islamabad's key ally, Saudi Arabia, and three other Middle East nations.

"At the moment there is nothing on Qatar issue, (we) will issue a statement if some development takes place," Zakaria said.
