The United States is worried that the dispute between Qatar and its neighbours is at an impasse and could escalate.
Saudi Arabia and other countries have imposed an economic blockade on Qatar, accusing it of sponsoring terrorism.
Qatar denies this and is refusing demands to close a Turkish airbase, downgrade ties with Iran and close the al-Jazeera television network.
US State Department spokeswoman Heather Nauert says there is a danger the dispute could worsen, but she says US diplomats are working hard with all countries involved.
