Secretary General of the Gulf Cooperation Council (GCC) Jasem Mohamed Albudaiwi strongly condemned on Tuesday the infiltration of members from the Iranian Revolutionary Guard Corps (IRGC) into Kuwait.
He said: "These hostile Iranian policies are a direct threat to the security and stability of the region and are a systematic attempt to destabilize regional peace and undermine the foundations of collective security."
"Such actions are in clear violation of the principles of international law, the United Nations (UN) Charter, and the principles of good neighborliness," he added.
He underscored "the full support of the GCC member states for Kuwait in all measures it takes to maintain its security and stability, as well as the safety of its citizens and residents."
Kuwait said on Tuesday that four people arrested earlier this month as they attempted to enter the country by sea confessed to belonging to Iran's Revolutionary Guards.
The four men -- two navy colonels, a captain and a lieutenant commander -- admitted they had been tasked by Iran's ideological army with "infiltrating" Bubiyan Island, Kuwait's interior ministry said in a statement.
The group attempted to enter on May 1 "aboard a fishing boat specially chartered to carry out hostile actions against Kuwait", the ministry said.
