Arab League Secretary-General Ahmed Aboul Gheit expressed regret on Monday that relations between Qatar and major regional powers had got to the point of suspending diplomatic relations.
Saudi Arabia, Egypt, United Arab Emirates and Bahrain cut relations with Qatar in a coordinated move. Yemen, Libya's eastern-based government, and the Maldives joined in later.
"Aboul Gheit is sorry things reached this point between several Arab states and is concerned about the ramifications these differences will have on joint Arab work," his office said in a statement.
A former Egyptian foreign minister, Aboul Gheit said he hoped Arab states would overcome their differences and present a united front against common threats to their national security.
He called on all sides to return to agreements reached in 2014, the last time matters between Qatar and its neighbours had reached a tipping point.
