The men who built the secret bomb factory had been clever — suspiciously so, Bahraini investigators thought, for a gang known mostly for lobbing molotov cocktails at police. The underground complex had been hewed, foot by foot, beneath the floor of a suburban villa, with no visible traces at street level and only a single entrance, hidden behind a kitchen cabinet.

But the real surprises lay inside. In one room, police found $20,000 lathes and hydraulic presses for making armor-piercing projectiles capable of slicing through a tank. Another held box upon box of the military explosive C-4, all of foreign origin, in quantities that could sink a battleship.

“Most of these items have never been seen in Bahrain,” the country’s investigators said in a confidential technical assessment provided to U.S. and European officials this past fall that offered new detail on the arsenals seized in the villa and in similar raids that have occurred sporadically over nearly three years. In sheer firepower, the report said, the caches were both a “game-changer” and — matched against lightly armed police — “overkill.”
