A senior Israeli official attended a maritime security conference in Bahrain on Monday in another sign of Gulf Arab nations and Israel transcending longtime enmities to focus on a perceived common threat from Iran.
The maritime workshop in Manama is the continuation of a Middle East conference held in Warsaw in February that Prime Minister Benjamin Netanyahu at the time called a "historical turning point" for an alliance against Tehran.

Dana Benvenisti, head of the Foreign Ministry's counterterrorism department, attended the Manama gathering in a rare visit by an Israeli official to Bahrain.
The United States is trying to build a global maritime coalition to secure vital trade channels following attacks on tankers in Gulf waters in May and June that Washington has blamed on Iran, a charge Tehran denies.
Tensions have risen since President Donald Trump last year withdrew the United States from a 2015 deal between world powers and Iran under which it agreed to curbs on its disputed nuclear program in return for the lifting of sanctions.
Washington has since reimposed a panoply of sanctions meant to strangle Iran's vital oil exports, and Tehran in turn has scaled back on commitments under the deal to restrict its uranium enrichment program.
"Aviation and maritime security are at top of the policy agenda in the region," Bahraini Foreign Minister Sheikh Khalid bin Ahmed Al Khalifa told the opening of the Maritime and Aviation Security Working Group.
In April, a group of Israeli businessmen and government officials canceled a planned visit to an economic conference in Manama due to what organizers said were "security concerns," following a social media campaign by Bahraini opponents of the visit.
In June, Bahrain hosted a "Peace to Prosperity" workshop meant to encourage investment in the Palestinian territories as the first part of a broader White House political plan to end the long-running Israeli-Palestinian conflict.
Last year, Oman hosted Netanyahu on a surprise trip, the first time an Israeli leader had visited the sultanate in 22 years. Foreign Minister Israel Katz subsequently visited the United Arab Emirates to attend a UN climate summit.
