Qatar is reviewing a list of demands presented by four Arab states imposing a boycott on the wealthy Gulf country, but said on Saturday the list was not reasonable or actionable.

"We are reviewing these demands out of respect for ... regional security and there will be an official response from our ministry of foreign affairs," Sheikh Saif al-Thani, the director of Qatar's government communications office, said in a statement to Reuters.

Saudi Arabia, Egypt, Bahrain and the United Arab Emirates, which imposed a boycott on Qatar, issued an ultimatum to Doha to close Al Jazeera, curb ties with Iran, shut a Turkish military base and pay reparations among other demands.

The statement said U.S. Secretary of State Rex Tillerson had recently called upon Saudi Arabia and the other countries to produce a list of grievances that was "reasonable and actionable."

"This list does not satisfy that criteria," it said.
