Four Arab states have refrained from slapping further sanctions on Qatar but voiced disappointment at its "negative" response to their demands and said their boycott of the tiny Gulf nation would continue.

Earlier today Qatar accused Saudi Arabia, the United Arab Emirates, Bahrain, and Egypt of "clear aggression" and said the accusations cited when they severed ties a month ago "were clearly designed to create anti-Qatar sentiment in the West".

The four Arab nations accuse Qatar of supporting terrorism and allying with regional foe Iran, which Qatar denies.

Their foreign ministers met in Cairo today after a deadline the four nations gave Qatar to meet 13 demands expired.

They had been expected to consider further sanctions at the gathering, but announced no new measures.

"The response the four states got was overall negative and lacked any content. We find it did not provide a basis for Qatar to retreat from its policies," Egyptian Foreign Minister Sameh Shoukry said, reading out a joint statement after the meeting.

"The political and economic boycott will continue until Qatar changes its policies for the better," Saudi Foreign Minister Adel al-Jubeir told a news conference.

Qatar's response to the demands has not been made public.
