DUBAI, July 17 (Reuters) - The United Arab Emirates was not responsible for an alleged hack of Qatari websites which helped spark a month-long diplomatic rift with Doha, the UAE's minister of state for foreign affairs said on Monday.

Speaking at a forum in London, Anwar Gargash also said the UAE would not escalate its boycott by asking companies to choose between doing business with it or with Qatar.
