Kuwait is reportedly shutting the Iranian cultural mission and related offices in the Gulf Arab state and reducing the number of Iranian diplomats stationed in the country.

The unspecified "actions" taken against the Gulf state’s diplomatic relationship with Iran comes following a court case ruling last year, when Kuwait convicted a group of men - one Iranian and the rest Kuwaiti - of spying for Iran and Lebanese Shi'ite Muslim group Hezbollah.

The official Kuwait News Agency (KUNA) announced the move in a brief statement Thursday. The Iranian ambassador to Kuwait has been notified, according to KUNA.

"The government of the state of Kuwait decided to take actions in accordance with diplomatic norms and in abidance with the Vienna conventions with regards to its relationship with the Islamic Republic of Iran," following the court ruling, acting Information Minister Sheikh Mohammad al-Mubarak al-Sabah said.

He gave no further details.
