The rockets went off in a field near the ceasefire line in the southern Golan Heights, AFP quoted an Israeli army spokeswoman as saying on Monday.
The rocket fire was "apparently connected to the situation inside Syria," she added, suggesting that foreign-backed militants might have fired the rockets.
"The Israeli army combed the sector the rockets fell in and informed the UN forces deployed in the Golan," the Israeli army spokeswoman said.
Israel captured the Golan Heights from Syria during the Six-Day War of 1967, when it also took control of the West Bank and the Gaza Strip.
It annexed the Golan Heights in 1981, although the move was never recognized by the international community and was a violation of international law.
The Syria crisis began in March 2011, and many people, including large numbers of soldiers and security personnel, have been killed in the violence.
The Syrian government says that the chaos is being orchestrated from outside the country, and there are reports that a very large number of the militants are foreign nationals.
In an interview recently broadcast on Turkish television, Syrian President Bashar al-Assad said that if the militants take power in Syria, they could destabilize the entire Middle East region for decades.
“If the unrest in Syria leads to the partitioning of the country, or if the terrorist forces take control, the situation will inevitably spill over into neighboring countries and create a domino effect throughout the Middle East and beyond,” he added.
