A Syrian soldier was killed and three other people were wounded on Wednesday night in an Israeli airstrike in the area of Palmyra in Homs Governorate, according to official Syrian media.

A Syrian military source told the Syrian Arab News Agency (SANA) that the strike had occurred just before midnight, and had been launched from the direction of Al-Tanf on the Syria-Iraq border.

The strike had targeted a communications tower and some adjacent positions, causing material damage in addition to the casualties, according to SANA.

According to the report, the strike was the second by Israel in as many weeks, following a “missile aggression” on Oct. 8 that targeted the Tiyas Military Airbase, also known as the T-4 Airbase. The T-4 base, the largest airbase in Syria, is also located in Homs Governorate, to the west of Palmyra.

U.K.-based war monitor Syrian Observatory for Human Rights, which has informants on the ground in Syria, reported on Thursday that four Syrian nationals were killed and seven wounded in the strike. The four who were killed had been working for Lebanon’s Hezbollah and Iran-affiliated militias, and the communications tower and other facilities targeted in the strike had belonged to the militias and were totally destroyed, according to the report.

The monitor group further reported that a member of the Syrian military had died of injuries sustained in the Oct. 8 strike, bringing the casualty figure for that incident to three, the other two having been militiamen. That strike, according to SOHR, had targeted a drone training facility.
