The Israeli army on Saturday said it treated five Syrians wounded in clashes on the Golan Heights and took them to a hospital inside the Jewish state.
According to a military spokeswoman, Israeli "soldiers provided medical care to five injured Syrians adjacent to the security fence" on the Golan Heights.
"The wounded were transferred to a hospital (in Israel) for further medical treatment."
The Israeli military army refused to say whether the Syrians were rebels or civilians and if they were later returned to Syria.
The Syrian Observatory for Human Rights said on Saturday that rebels overran a military police checkpoint at the Golan Heights town of Khan Arnabeh just beyond the outer ceasefire line along the demilitarised zone bordering Israel.
Regime forces responded by shelling Khan Arnabeh and the nearby village of Jubata al-Khashab, inside the ceasefire zone.
The Golan has been tense since the outbreak nearly two years ago of anti-regime protests in Syria that quickly turned into a bloody insurgency, at times spilling over with mortar and gunfire into the Israeli-held zone.
Last November, Israel responded with artillery after gunfire from Syria hit an army vehicle but caused no injuries, in the first instance of Israeli fire directed at the Syrian military in the Golan since their 1973 war.
Israel seized the Golan from Syria in the 1967 Six-Day War and annexed it in 1981, in a move never recognised by the international community.
