Bahrain's Interior Ministry on Saturday evening announced it had arrested two Gulf Arab citizens suspected of plotting "terror" attacks against the Kingdom .
The two Gulf nationals reportedly tried to enter Bahrain using fake passport through the Kind Fahd causeway - which connects Bahrain to Saudi Arabia - and had a large amount of money in their possession, the ministry said late Saturday, according to Reuters.
"The initial investigation revealed that the arrestees are former detainees of the Guantanamo detention center. They are suspected of plotting a terror act to jeopardize the security and safety of Bahrain," the ministry statement added.
The statement did not elaborate further on the nature of the planned attacks and did not shed further light on the identities of the Gulf nationals arrested, according to Reuters.
Bahrain, a staunch ally of the West  and the home to the US Navy's Fifth Fleet , has been rocked by political and social unrest since protests led by the Shiite majority broke out in 2011 .
The protests, which began in February 2011, were quelled by the government with help from Saudi Arabia and other Sunni-led Gulf states. Clashes and violence have persisted, and mediated talks between the government and the opposition have failed to resolve the unrest.
