The US has urged Qatar's local rivals to air their grievances with the tiny Gulf kingdom in the hope of ending the ongoing diplomatic crisis.
Five countries - Saudi Arabia, Bahrain, the United Arab Emirates, Yemen, and Egypt - cut ties with the Qatari government over allegations it was supporting militia groups to bolster instability in the Persian Gulf.
A number of this five have banned social media support for Qatar, or any criticism of the other countries that have ended their relationship with it - despite the Qatari government refuting the allegations.
Washington has been attempting to mediate the growing diplomatic crisis.
Addressing reporters, Rex Tillerson said it was understood a list of demands was being prepared by the five countries, and called for it to be presented to Qatar in a "reasonable and actionable" manner.
The US Secretary of State explained it had always been the desire of the US to have unity in the Persian Gulf in order to concentrate on the fight against "terrorism."
Meanwhile, US president Donald Trump is believed to have discussed the crisis with the new Crown Prince of Saudi Arabia, according to a White House statement.
