Israeli soldiers reported sporadic light arms fire from across the Syrian border on the Golan Heights Sunday night.
The bullets caused neither injuries nor damage.
Troops stationed at a lookout post on Tel Hazeka, near the community of Alonei Habashan, said the shots appeared to have been stray rounds from clashes inside Syria.
On Saturday night a similar incident occurred in the same area. Israel lodged a complaint with the United Nations over the shootings.
In February a Syrian tank shell landed in the Alonei Habashan community but did not explode. Sappers later disarmed the shell, also believed to have been a stray round fired during a battle across the border in the Syrian civil war.
Since the beginning of the year there have been a number of incidents of cross-border fire, some deliberate. Last week an Islamist Palestinian group claimed responsibility for several mortar rounds that were fired at Mount Hermon from Syria, without causing injury or damage.
Although IDF troops did not return fire on that occasion, in the past few months Israeli forces have fired missiles and tank rounds at Syrian targets in response to deliberate fire aimed at IDF positions or Israeli communities.
