The Kuwaiti Ministry of Foreign Affairs says it delivered a “protest note” to Iranian envoy Mohammad Tutunji, after the alleged “infiltration” of a group of armed Islamic Revolutionary Guard Corps (IRGC) members in the Gulf country, Al Jazeera reports.

Kuwait’s deputy foreign affairs minister, Hamad Suleiman al-Mashaan, reiterated the country’s “strong condemnation of this hostile act” and demanded that Iran “immediately and unconditionally cease such actions”, the ministry says in a statement.

Al-Mashaan describes the incident as a “blatant violation of Kuwait’s sovereignty”, as well as a violation of international law and the UN Charter, and stressed that Kuwait has the right to self-defence.
