A mortar shell from Syria exploded in the Israeli-occupied sector of the Golan Heights plateau on Thursday, the military said.
"There was no damage or injuries and the soldiers conducted a sweep in the area of the blast," a military spokeswoman said.
She added that the blast was "apparently linked to the internal situation in Syria" in an indication the army viewed it as stray fire and not intentionally directed at Israel.
The Golan has been tense since the beginning of the conflict in Syria more than two years ago, but so far, there have only been minor flare-ups as Syrian small arms fire or mortar shells hit the Israeli side, which has on occasion prompted an Israeli response.
Israel, which is technically at war with Syria, seized 1,200 square kilometres (460 square miles) of the strategic plateau during the 1967 Six Day War, which it and later annexed in a move never recognised by the international community.
