Kuwait on Tuesday summoned its ambassador to Iran following attacks on the Saudi embassy in Tehran and its consulate in Mashhad during protests against the Saudi execution of a Shia cleric.
"Such action constitutes a flagrant breach of international conventions and violation of Iran's commitment to security and safety of diplomatic missions on its lands," Xinhua cited official with Kuwaiti foreign ministry as saying.
On Saturday, Saudi Arabia announced the execution of prominent Shia cleric Nimr al-Nimr along with 46 other men over terror charges.
Later on the day, angry mobs in Shia-dominated Iran stormed and set ablaze Saudi Arabia's embassy in Tehran and consulate in Iran's religious city of Mashhad to protest al-Nimr's execution.
On Sunday, Saudi Arabia cut off diplomatic relations with Iran over the attacks and for what it said was an Iranian interference in its affairs.
On Monday, Bahrain and Sudan announced severing of relations with Iran citing Tehran's intervention in Arab affairs.
Also, the United Arab Emirates (UAE) on Monday downgraded its diplomatic relations with Iran and reduce the number of Iranian diplomats in the country.
