Qatar accuses UAE of hack that sparked Gulf crisis

"The information published in the Washington Post ... revealed the involvement of the United Arab Emirates (UAE) and senior Emirati officials in the hacking of Qatar News Agency," its government communication office said in a statement.

The report "unequivocally proves that this hacking crime took place", it added.

The UAE's minister of state for foreign affairs Anwar Gargash said earlier on Monday that the Washington Post report was false and denied his country's involvement in any hack.
