Bahrain has summoned Iran's charge d'affaires to protest against what it called a "gross violation of its sovereignty" in a row after Tehran criticised efforts by Gulf Arab states to forge closer political and military union.
Heads of state met in Riyadh on Monday to discuss a call by Saudi King Abdullah to unite the six-member Gulf Cooperation Council (GCC) to counter Iran's growing influence in the Middle East and neutralise any threat of revolts by Shia communities in their countries.
They failed to agree on further integration but talks on the matter are to resume later this year.
