Four pro-Hezbollah fighters were killed on Friday in an Israeli drone strike on their car in the south of Syria, a war monitor said.
The four fighters "working on behalf of Hezbollah" were killed in Madinat al-Baath town in the province of Quneitra, close to the Israeli-annexed Golan Heights, the Syrian Observatory for Human Rights head Rami Abdel Rahman told AFP.
The monitor was unable however to confirm if the combatants were Syrian or not, but they were not part of the Syrian army, Abdel Rahman said.
The day before, the Observatory, which has a network of sources in Syria, reported that Israel hit sites close to Damascus with eight missiles, as well as a "regime military post in the province of Quneitra", without causing any casualties.
The strikes were a response to the bombardment of Israeli-annexed Golan, the monitor said.
There was no comment from Israel on the drone strike. Israeli government spokesperson Eylon Levy said Friday that the Israeli military struck a number of targets in Syria in response to two launches on Thursday that fell in open areas.
