Direct Hamas hit Tuesday to an Ashkelon home with a new weapon left 70 people injured, 29 seriously. The 345mm missile with an extra-large warhead was not known to be present in the Hamas arsenal. It was used for the first time on the 50th day of the Gaza conflict to cause the largest number of Israeli casualties of any single rocket so far and the greatest damage. Two neighboring houses were completely leveled and dozens of buildings within a wide radius damaged. The IDF is investigating the provenance of the deadly new rocket.
