At the same time, the Post report says it is still unclear if it was UAE hackers who carried out the attack or if it was "contracted" to foreigners.
Anwar Gargash, UAE Minister of State for Foreign Affairs said in a statement that worldwide monitoring was needed in the standoff between Qatar and its Arab neighbours. The boycott has caused turmoil in the oil- and gas-rich emirate, which is dependent on imports by land and sea for the basic needs of its population of 2.7 million.
The incident took place on May 24, as the state-run Qatar News Agency website attributed explosive remarks to the country's Emir Sheikh Tamim bin Hamad Al-Thani.
In late June, Kuwait, as a mediator in the crisis, handed over to Qatar the ultimatum of the four Arab states with 13 demands, including the requests to severe Doha's relations with Tehran, close Turkey's military base in Qatar and shut down the Al Jazeera TV channel, as well as to end support for the Muslim Brotherhood, a terrorist organization banned in Russian Federation.
The United Arab Emirates (UAE) on Monday denied reports that it was behind a series of hacks that sparked regional discord that isolated Qatar from its neighbors.More news: Windows 10 Creators Update incompatible with certain PCs already running Windows 10
UAE Ambassador Yousef al-Otaiba denied the report in a statement, saying it was "false", the Post said.
Shortly after the hack, citing the emir's reported comments, the UAE, Saudi Arabia, Bahrain and Egypt blocked all Qatari news sites and severed ties with Qatar. It continued: "What is true is Qatar's behaviour". Funding, supporting, and enabling extremists from the Taliban to Hamas and Qadafi. However, Qatar has so far not come out with any such evidence.
Saudi Minister of Foreign Affairs, Adel Bin Ahmed Al Jubeir, said that the Foreign Ministry will provide the French Ministry for Europe and Foreign Affairs with a complete file of negative actions carried out by Qatar over the years, referring to also providing the American side and other countries with the same file.
The FBI was previously known to be working with Qatar to investigate the hacking.
"I understand the concern of our allies", he added.
