Really not all that surprising, is it?

Via Al Arabiya:

Police in Bahrain said on Wednesday they uncovered a weapons cache inside an unlicensed mosque where locally-made bombs were being produced.

Authorities said they seized electric detonators, stopwatches and other materials used to make bombs.

The cache was uncovered in the area of Abou Baham, a scene of violence attributed by official media to Shiite hardliners.

On Sunday authorities detained seven men over the killing of a policeman, as demonstrators tried to break through police checkpoints around the village where he lost his life.

Bahrain, which hosts the U.S. Fifth Fleet, has been convulsed by unrest since February last year following mass demonstrations led by majority Shi’ites demanding democratic change in the Sunni-led monarchy.
