The group was targeting the 200,000 barrels per day refinery and the state security building, as well as a U.S. army camp, daily newspaper al-Anbaa reported, citing unidentified sources it said were familiar with the investigation.
The attacks were planned to take place in the Muslim holy month of Ramadan, it added. Ramadan is due to begin later in August.
Kuwait said on Tuesday it had foiled a plan by a six-member Qaeda-linked cell to bomb the Arifjan U.S. army camp (photo)and "important facilities," but gave no further details on the other potential targets.
Members of the group, led by a surgeon at one of the Gulf Arab state's hospitals, had confessed to planning attacks aimed at pressuring the U.S. to withdraw troops from Kuwait, the paper added.
