Palestinians have managed to use during the cease-fire to improve their rockets. One of two improved Kassam rockets were launched and smashed into an Ashkelon school, luckily on Saturday, in an attack that tore through the school and destroyed classrooms.
In all, seven rockets were launched over the weekend, most hitting open fields. Police said terrorists in Gaza assembled the rockets that struck Ashkelon using an improvised technique to make them more powerful.
The two rockets had a 170-mm. diameter, which allowed for a greater amount of explosives to be packed inside.
"These are improved Kassams, more powerful than standard Kassams. They have a longer range and pack a bigger punch," a police source told The Jerusalem Post.
