The auto bomb hit the outskirts of the village of Hader, which lies near the disengagement line that divides the Syrian-controlled part of the Golan from the area occupied by Israel, the regime's SANA news agency stated.
It said the death toll was likely to rise as most of the wounded sustained serious injuries and had to be pulled out of the debris with difficulty in the face of gunfire and shelling by rebel fighters.
There are an estimated 20,000 Druze living under the Israeli-occupied portion of the Golan Heights which was captured from Syria in the 1967 Six Day war and was de facto annexed by Israel in the early 80s.
The retraction, the statement added, came "under pressure from Druze reactions in Israel" to "the suspicious relationship between the regime in Tel Aviv" with al-Qaeda and al-Nusra.
Hader, a town just inside Syrian territory, is reportedly being targeted by the Nusra Front, formally known as Jabhat Fateh al-Sham. The army said they damaged "security infrastructure" in the process.
On other occasions, it has been accused of carrying out air strikes targeting weapons intended for Hezbollah, the Lebanese militant group that is an ally of Damascus but has fought Israel. Reports Friday afternoon said that the rebel groups had been beaten back and had retreated out of the village.

Israeli army spokesman, Brigadier General Ronen Manelis, said the military was ready to "prevent Hader from being harmed or occupied, as part of our commitment to the Druze population".
In Majdal Shams, Druze residents gathered along the buffer zone seeking to cross over and help.
The Israeli army sealed off the area to prevent anyone crossing.
The IDF statement reflected ongoing pressure on Israeli leaders from the Druze communities in the Galilee and on the Golan to help their coreligionists across the border who are often caught in the crossfire between Sunni rebels and Alawite and Shiite pro-government forces.
After the mounting accusations, Israel showed exceptional interest in Khodr, with Prime Minister Benjamin Netanayahu telephoning Defense Minister Avigdor Lieberman to announce his support for the Druze community. "And we also seek to protect our Druze brothers".
The policy has been controversial, and in 2015, members of the country's Druze minority attacked two ambulances transporting Syrians, killing one and injuring another.
