Count me more skeptical of anything Al Jazeera reports than I am even of the Dim media in the U.S. Especially this early.
I believe it is possible that car batteries did explode. They now make lithium replacement batteries for standard batteries in cars. That would fit the profile of all the other devices. Like someone else mentioned, all lithium batteries. Lithium is an explosive when in the proper conditions. An optimum energy blast designed to target lithium batteries would surely do exactly what happened.
