In a letter to the UN General Assembly circulated today, the 11 countries cited Iran's support for Shiite Houthi rebels in Yemen and the Shiite Hezbollah group in Lebanon which has sent fighters to support the Syrian government.
They also accused Iran of supporting "terrorist groups and cells" in Bahrain, Iraq, Saudi Arabia, Kuwait and elsewhere.
They reiterated a statement by Bahrain's foreign minister in September that the only way forward is for Iran "to comprehensively change its foreign policies and end hostilities."
