Israeli police spokeswoman Luba Samri said the rockets landed in open areas near the Gazan border early Sunday and did not cause injuries.
The exchange shows cracks in the shaky cease-fire that Egypt brokered to stop a barrage of rockets and air strikes between Israel and the Gaza Strip last month.
Militant groups in Gaza frequently launch rockets into Israel but rarely inflict casualties. There are many small factions, and cease-fires reached by some does not mean others abide by them.
Another rocket landed Thursday in the southern Israeli city of Eilat near the Egyptian border. Israel says it was fired from Egypt.
