"We are ready to exchange experiences with Saudi Arabia and other moderate Arab countries and exchange intelligence information to confront Iran", Eisenkot said in his first-ever interview with an Arabic newspaper, adding "there are many shared interests between us and Saudi Arabia".
Sunni Muslim powerhouse Saudi Arabia and Iran, the predominant Shiite power, have for decades stood on opposing sides of conflicts in the Middle East including in Syria and Yemen. Riyadh, with which Tel Aviv does not have diplomatic ties, is not the only not so obvious Israel's partner in the region, the minister proffered, adding that his country is "usually the party that is not ashamed" of such contacts.
A senior Israeli official has said Tel Aviv has "partly covert" ties with "many Muslim and Arab countries", including Riyadh.
Saudi Foreign Minister Adel al-Jubeir warned Iran that Riyadh "will not hesitate to defend its national security to keep its people safe", in opening remarks at the meeting.
Arab foreign ministers are holding an emergency meeting at the Arab League headquarters in Cairo, following Saudi Arabia's request to discuss Iran's "violations" and its role in "undermining Arab security and peace". Alluding to the November 4 attack targeting Riyadh, he said the attack delivered a message to Arab nations that their capitals were within the range of Iranin missiles.
Gulf Arab countries are also anxious about the Islamic republic's support for Huthi rebels in Yemen.
The ministers, according to the final statement, said they supported any action to be taken by Saudi Arabia to protect its national security, within the boundaries of global legitimacy.
Arab League chief Ahmed Abul Gheit said Lebanon was among the countries that voted in favour of the resolution, except for the points in which Hezbollah was mentioned.
Lieberman called on the Arab world to follow Egypt's Sadat and make peace with Israel, on the way to countering a shared foe - Iran.
The House of Saud has been losing ground in the multi-religious Mediterranean state, and the Bahraini foreign minister at the Arab League summit called Lebanon's Hezbollah militia "Iran's longest arm in the region".
Saudi Arabia's powerful Crown Prince Mohammed bin Salman has accused Iran of "direct military aggression" against the kingdom by supplying the Yemen rebels with ballistic missiles, but Tehran has denied any involvement.
The IDF chief of staff said that US President Donald Trump's harsh stance on Iran allowed for a new chance to build a regional alliance of Arab states and to develop a strategy to stop Iran's expansion.
Iran-backed Hezbollah - which is dominant in Lebanon - is also a great enemy of Israel, with which it fought a war in 2006.
A source close to Hariri said the Cairo meeting aimed to "continue the series of Arab and global consultations".
