Dubai: Bahrain’s interior ministry said that it had arrested 28 people, including individuals convicted in absentia on terrorism charges and sentenced to life in prison.

“Some of those arrested have had their nationality revoked,” the ministry said in a statement late on Monday.

“Some of them were charged in more than one case that involved planning and carrying out terrorist acts with the aim to undermine the security of the country. The investigation foiled a number of terrorist operations planned in various villages.

The investigation included tracking individuals and monitoring their safe houses by a specially trained surveillance team, the ministry added.

“The operation was a coordinated effort by various investigation units in the country. The General Directorate of Criminal Investigation and Forensic Science has initiated legal proceedings to refer those arrested to the Public Prosecution,” the statement carried by Bahrain News Agency (BNA) said.

The cases listed by the ministry included bomb blasts, the formation of a terrorist cell, making bombs equipped with cell phone detonators, and the planting of explosives in several areas.

Other cases involved planting fake bombs and suspicious objects, attacking police with Molotov cocktails, arson and blockading roads.
