Several people suffered shock and were treated on the spot by Magen David Adom paramedics.
A team of police sappers also arrived at the scene, to make sure the rocket shrapnel did not pose threat to the residents.
Sderot's parents association has been threatening not to allow the school year to open in the town on September 2, due to the government's failure to complete the fortification of classrooms and schools.
However, Major-General Yitzhak Gershon, head of the Home Front Command, stated Wednesday that, "We have plenty of fortified classrooms so I see no reason not to open the school year on time."
Sasson Sara, head of the Sderot PTA, responded by saying, "If the situation is so good and there are so many fortified classrooms, why don’t the major-general or defense minister sign a guarantee for the classrooms. This is nonsense. I would like to know if the major-general would send his children to study in a bomb shelter for eight hours. Does he understand what this means?"
