Anti-aircraft shells were launched from Syria toward Mount Hermon on Thursday, the Israeli army said, but failed to reach Israel and caused no damage.
The incident is being looked into, the statement said.
This launch follows a similar incident on Saturday night, when two rockets were fired at the Golan Heights, one of which hit a ski resort and damaged a chairlift cable. The other fell on Syrian soil.
In response to the rocket fire, the Israel Defense Forces struck a number of a number of military targets in Syria overnight which was later confirmed Sunday.
Syrian state media reported that three Syrian soldiers were killed and seven were wounded in the strike, while the Syrian Observatory for Human Rights reported that 10 were killed, seven of which were Iranian and Hezbollah militants.
Another outlet, aligned with the Assad regime, reported that five Syrians were killed. The Syrian government has not confirmed either report.
