Three Qassam rockets were fired Tuesday from the Gaza Strip towards Israel.
One of the rockets landed near a northern Negev kibbutz and another hit the fence of a strategic facility in Ashkelon's industrial area, south of town.
The third rocket fell in an open field.
Upon hitting the facility's fence, the rocket set off the "Color Red" alert system and workers were asked to enter protected areas.
One of the employees told Ynet, "We heard a very loud explosion and the siren at the factory was activated. The rocket hit the fence, very close to a sensitive location. I can say that very big disaster had been prevented."
"Unfortunately, this is the reality around here. There are quite a few strategic facilities in the area, and rockets land here all the time. But it sometimes seems that no one cares," he added.
On Monday defense Minister Amir Peretz announced that a rocket interception system selected by the army will be put into use in the Sderot area first, and only later in other areas.
