Kuwait became Tuesday the latest Gulf Arab state to recall its ambassador from Iran to protest attacks on Saudi diplomatic missions, while also summoning Tehran's ambassador to express its disapproval of them.
However, the emirate did not expel the envoy or downgrade the level of diplomatic relations with Iran.
Deputy Foreign Minister Khaled al-Jarallah said the ambassador was handed a memorandum that condemned the attacks and called for Iran to "respect its international obligations," according to the official KUNA news agency.
He also expressed Kuwait's support for Saudi Arabia in the measures it is taking to safeguard its security.
In announcing the recall, the foreign ministry was quoted by the official KUNA news agency as saying the attacks "represent a flagrant breach of international agreements and norms and a grave violation of Iran's international commitments for the security of diplomatic missions and the safety of diplomats".
The announcement comes after Sunni-led Saudi Arabia and Bahrain severed ties with predominantly Shiite Iran this week.
And the United Arab Emirates has recalled its ambassador and downgraded ties with the Islamic republic.
Bahrain, Kuwait, Saudi Arabia and the UAE are members of the Gulf Cooperation Council, along with Oman and Qatar.
Kuwait has maintained good relations with Tehran despite busting in August a cell allegedly spying for Iran.
Around a third of Kuwait's native population of 1.3 million is Shiite.
Relations between Riyadh and Tehran were already strained over their support for opposite sides in conflicts in Syrian and Yemen, and were exacerbated over Saudi Arabia's execution of a prominent Shiite cleric.
