If they used hollow blocks, the explosion would have done the same damage except that you will now have thousands of smaller fragments weighting from a few grams to a few kilograms capable of flying further than the wall panel traveled to the van. Each of the larger fragments would be more than enough to seriously hurt or even kill a person on the street across from the explosion. Given that, it would be a worst alternative if hollow blocks were used.
