An Israeli airstrike in central Syria killed a Syrian soldier and three pro-Iranian fighters on Wednesday, a Britain-based war monitor said.
The Syrian state news agency SANA had previously quoted a military source as saying that the attack near the city of Palmyra in Homs province killed one soldier and wounded three others.
“Around 23:34 (2034 GMT) the Israeli enemy carried out an air attack … in the Palmyra area targeting a communication tower and various positions in its vicinity,” the source told SANA.
The Syrian Observatory for Human Rights, a UK-based monitor, said the attack targeted several Iranian positions, including the communications tower near the T4 airbase east of Palmyra.
It reported that a Syrian soldier and three pro-Iranian fighters were killed in the attack, but their nationality was not immediately clear.
Seven others, including three Syrian soldiers, were injured.
Last week, an Israeli missile attack on the same air base killed two pro-Iranian foreign fighters, the Observatory reported.
SANA said six soldiers were injured in that attack.
Since the outbreak of the Syrian civil war in 2011, Israel has routinely carried out airstrikes inside Syria, mainly against Syrian government troops, as well as Iranian and Lebanese Hezbollah forces allied to the Damascus regime.
The Israeli military rarely acknowledges individual strikes, but has repeatedly said that it will not allow Syria to become a stronghold for its arch enemy Iran.
