A rocket fired from Beit Hanoun in the Gaza Strip hit a factory in the Sderot industrial area on Saturday, causing it to catch on fire.
A second rocket fell in an open area near Sderot. In a second attack later in the evening, two additional rockets hit open areas in the Sdot Negev Regional Council.
No one was hurt from any of the rockets, but the factory was burned to the ground.
Four workers who were inside the factory when the rocket hit managed to escape. Two of them, 23 and 59 years old, were taken to the Barzilai Medical Center in Ashkelon suffering from light burns.
The fire in the factory led to smaller explosions inside the factory, caused by paint canisters that caught on fire.
After about two hours, firefighters managed to put the fire out completely, and then began assessing the damage caused to the factory.
Earlier, a Code Red siren was sounded in Sderot and in the Hof Ashkelon Regional Council. A 50-years-old man suffered blast injuries after tripping on his way to a safe room at the sound of the Code Red siren, and was taken to the Barzilai Medical Center in Ashkelon.
"The city's residents are not deterred by the heinous and cowardly actions of terrorists who are firing rockets from Gaza towards civilian populations," Sderot Mayor Alon Davidi said. "We stand strong in order to give the prime minister, defense minister and the IDF full backing in the operation to bring the boys back home and restore order."
On Friday evening, six rockets were fired into from Gaza into Israeli territory and a mortar shell exploded near the border fence between Gaza and Israel. Two of the rockets fired were shot down by the Iron Dome anti missile system while the other four fell in open areas in the Eshkol Regional Council. No damage or injuries were reported as a result of the rockets or mortar fire.
The Israeli Air Force attacked four terror targets in the Gaza Strip overnight Friday in response. IAF aircrafts struck two terror activity sites, a weapon manufacturing site in the central Gaza Strip and a weapons storage site in the southern Gaza Strip, the IDF said. Direct hits were confirmed on all targets.
On Friday morning, a military vehicle was lightly damaged by an explosive device near the Gazan border fence. IDF tanks responded with fire on suspected militant positions.
Protests in Umm al-Fahm also brought clashes between police and Palestinians Friday as several hundred took to the streets against IDF actions in the West Bank.
