A Thai foreign laborer was lightly wounded by shrapnel after a Qassam rocket crashed into a field in the Eshkol Regional Council on Sunday afternoon.
Paramedics treated the man at the scene before evacuating him to the Soroka Hospital in Beersheba for treatment.
The al-Quds Brigades, the military wing of the Islamic Jihad, claimed responsibility for the firing of four rockets towards southern Israel.
A short hour before the barrage, Deputy Defense Minister Matan Vilnai paid his respects to the family of 51-year-old Amnon Rosenberg in Kibbutz Nirim. Rosenberg was killed last week when a Palestinian mortar shell hit the Nirlat paint factory in Kibbutz Nir Oz where he was employed.
"The Palestinians are leaving us no choice, with every day we move closer to launching a large-scale military operation in Gaza," said Vilnai.
Immediately following the Shavuot holiday this week the cabinet will vote on the possibility of such an operation.
Should Hamas and the other terror groups use the holiday to increase their attacks, it will increase the pressure on the government to order a military response.
