A mortar shell launched from Syria landed on the Israeli-controlled side of the Golan Heights Tuesday morning, the third since the night before, an Israeli military spokeswoman said, dpa reported.
The two previous mortar shells struck Monday night.
The Israeli army had said the projectils that landed Monday were rockets, but the spokeswoman told dpa Tuesday they had, in fact, been mortars. They all landed in open fields, causing no injuries or damage.
They appeared to have been stray shots fired during the ongoing domestic violence in Syria, she told dpa, citing "initial evidence.
" They were not believed to be linked to Israel's Saturday night airstrike outside Damascus.
Passenger and light planes were flying again in northern Israel Tuesday, after the military reopened the airspace to civilian aviation. The airspace was closed Sunday as a precaution against possible Syrian retaliation for the massive airstrike on a military complex outside Damascus.
Israel has not confirmed or denied that it carried out the airstrike, as well as another on Thursday night, to destroy a shipment from Iran of missiles with a 300-kilometre range to the radical Shiite Hezbollah movement in Lebanon.
According to the Syrian Observatory for Human Rights, the Saturday night airstrike - which was larger than the Thursday one and, according to witnesses, sparked bigger explosions than seen or heard in the vicinity of Damascus in the two years of internal conflict - killed at least 42 Syrian soldiers.
A Britain-based group of Syrian anti-regime activists said about 150 soldiers are normally stationed in the area that was targeted, but that it was not clear how many were there at the time of the strike. Its sources at Syrian military hospitals provided it with the reported death toll, the group said.
