Four Qassam rockets landed in open areas in the western Negev Sunday morning. No injuries were reported in the attack.
Two of the rockets landed near Sderot and two other fell close to the border near the southern part of the Gaza Strip.
During the weekend, five Qassams were fired at Israel. Two rockets landed in Sderot on Saturday, one hitting a house whose inhabitants were out at the time of the strike. No one was injured.
The town's residents reported that the Color Red alert system did not go off during the attack.
On Friday, three rockets landed in open fields in the Negev.
Hamas' political leader Khaled Msahaal declared this weekend that his organization would not agree to halt rocket fire on Israel in exchange for an easing of travel restrictions on the Palestinians.
Mashaal was referring to a US document proposing a May-to-August timeline for easing Palestinian movement and improving Israeli security.
"I swear it's a joke ... The equation has now become: dismantling the checkpoints, in exchange for (giving up) resistance," he said. "This has become the Palestinian cause".
