Shots fired from Syria hit the central Israeli-occupied Golan Heights, a military spokeswoman said yesterday, causing no harm or damage.
The spokeswoman said the shots were from small arms, and "most likely were stray bullets, we don't know if it was intentional".
Israel submitted a complaint to the UN force in the region.
The Golan Heights have been tense since the start of the conflict in Syria more than two years ago.
But there have been only minor flare-ups in the region to date, with Syrian shells crashing in the occupied Golan and Israel firing in retaliation.
Last week, projectiles from Syria hit Mount Hermon, which caused the popular site to close down for visitors.
Israel, which is technically at war with Syria, seized 1,200 square kilometres of the strategic Golan Heights in the 1967 six-day war, which it later annexed.
