An Interior Ministry statement said all six members of the al Qaeda-linked cell had confessed after being arrested. It did not say if the targeted facilities included oil industry plants in Kuwait, the world's fourth-largest oil exporter.
"The state security has uncovered a terrorist network following al Qaeda, and includes six (Kuwaiti) citizens who have planned to carry out a plan to bomb Arifjan Camp, the state security building and other important facilities," the ministry said.
Camp Arifjan is located south of Kuwait and serves as a staging ground for forces deploying in Iraq.
Kuwait, the launch pad for the 2003 U.S.-led war on Iraq which ousted Iraqi leader Saddam Hussein, remains a logistics base for the U.S. army to support its troops in Iraq.
Al Qaeda has waged attacks in the Gulf Arab state in recent years but a crackdown by governments in the region has succeeded in preventing fresh violence, such as bombings of foreign housing complexes and oil sites in several Gulf Arab states including Saudi Arabia.
