Jerusalem: Rocket fire from Syria slammed into the Israeli-occupied sector of the Golan Heights Sunday but there were no reports of casualties.
"At least five rockets fired from Syria hit different locations across the Golan Heights," the Israeli army said in a statement.
An army spokeswoman told AFP that it was not known who launched the rockets and the Israeli military did not return fire.
She said there were no casualties in the attacks, at around 1:30 am (2230 GMT) on Sunday, the 48th day of a war between Israel and the Islamist movement Hamas in and around Gaza.
Last month a rocket from Syria prompted Israeli artillery to shell Syrian army positions.
In June Israeli warplanes attacked Syrian military headquarters and positions after an Israeli teenager was killed in what the Jewish state said was a cross-border attack by forces loyal to the regime of Syrian President Bashar al-Assad.
Some previous incidents have been put down to stray fire from fighting between Syrian government troops and opposition forces.
Late on Saturday, a rocket fired from Lebanon hit northern Israel.
There was no immediate claim of responsibility for the launch or reports of damage or injuries.
A Lebanese security source said the rocket was fired from Dheira, three kilometres (nearly two miles) from the border with Israel.
The same source noted that Israeli helicopters were seen flying around the border area.
In mid-July, at least nine rockets were fired from Lebanon at the Jewish state, prompting Israel to retaliate with artillery fire.
Lebanese military officials had at the time said they believed the attacks were carried out by a small Palestinian group in an act of solidarity with Gazan militants.
Israel did not return fire for the Saturday night attack but sent "a strong protest" to the United Nations Interim Force in Lebanon, which monitors the border between Lebanon and Israel.
