It was reported that hospitals are taking out ball bearings. In one report on terrorist bomb making, here is a description on the subject of ball bearings:

The most widely used and the most dangerous shrapnel consists of ball bearings 3-7 millimeters in diameter. In the most severe terrorist acts – in the Delfinarium, Sbarro, in the banquet hall in Netania – the bombs of the suicide-bombers were filled with steel balls.

The Israelis have suffered for years from these extremist Islamic savages.

The use of ball bearings in explosive devices is hardly some recent profound innovation, or some sort of signature unique to certain types of bombmakers.
