"In response to the rocket fire, IDF artillery targeted two military posts of the Syrian Armed Forces in the central Syrian Golan Heights," an army statement said, AFP reported.
The statement did not specify if the posts were hit.
Since the Syrian conflict erupted in 2011, the Golan has been tense, with an increasing number of mostly stray rockets and mortar rounds hitting the Israeli side, prompting the occasional armed response.
Israel had earlier claimed that two "stray" rockets hit the area of the Golan Heights it controls, without causing casualties or damage.
Israel seized 1,200 square kilometres (460 square miles) of the plateau in the Six-Day War of 1967 and later annexed it in a move never recognized by the international community.
