Three mortar shells were fired from Syria into northern Israel.
The shells, which landed Thursday and did not cause any injuries or damage, were not believed to have been targeting Israel and likely were fired by the Syrian army at rebel forces in the area.
The Israel Defense Forces reportedly filed a complaint about the incident with United Nations forces in the demilitarized zone on the border between Israel and Syria.
It was the third incident between Syria and Israel in the last week; all are believed to be a result of the Syrian civil war.
In all three cases, Israel's military filed a complaint with the relevant U.N. peacekeeping forces.
