Qatar said it believed a media report citing USA officials had revealed the responsibility of the United Arab Emirates in an alleged hack on its state news agency in late May which helped spark a diplomatic rift between Doha and its neighbors.
The Post said officials became aware of the UAE's role in the hack after newly analyzed information gathered by members of the USA intelligence community revealed senior members of UAE's government discussed the plans and how to implement the attack. The Emirati ambassador to the United States, Yousef al-Otaiba, was also quick to deny the report.
"What is true is Qatar's behavior. Inciting violence, encouraging radicalization, and undermining the stability of its neighbors", the statement said. In response, Saudi Arabia, the UAE, Egypt and Bahrain cut diplomatic and transport ties with Qatar on June 5, accusing it of supporting "terrorism".
"UAE had no role whatsoever in the alleged hacking described in the article", he said in a statement.
Qatar said in late May that hackers had posted fake remarks by the emir, an explanation rejected by Gulf states.
The Washington Post story also comes days after the USA secretary of state Rex Tillerson spent four days engaged in shuttle diplomacy between Kuwait, Qatar and Saudi Arabia - all strategic U.S. partners - seeking to find a way to resolve the crisis.
Officials also noted that it is not yet known whether or not the UAE committed the hack itself, or contracted another party to have them carried out. Doha had previously asked United States and British officials to investigate the source of the hack.

"The Washington Post story is not true, purely not true", he said responding to a question after a speech at Chatham House in London.
The hacks took place almost two weeks earlier on May 24, one day after senior Emirati officials allegedly discussed the plan. The move has left the Gulf kingdom effectively isolated in the region.
Qatar has been subjected to a diplomatic and economic blockade that the USA government says could compromised U.S. efforts against so-called Islamic State.
With US spy agencies now apparently briefing against them, Qatar's antagonists may conclude US sympathy for their position is rapidly dwindling.
"It's denial after denial after denial".
"We have some leads that there are some countries involved, part of them - they are part of the countries that will impose this blockade against Qatar", al Thani told CBS News in June.
