Syria accused Israel of launching an airstrike against a military installation near Damascus overnight in which eight Iranians were allegedly killed, Ynet reported Wednesday.

The reported airstrike targeted an installation in the Al-Kiswah region southwest of Damascus. Israeli is believed to have struck that base in December of last year.

The apparent Israeli attack came after the IDF gave orders to open public bomb shelters in the Golan Heights after reports of “irregular Iranian movements” inside Syria. There are concerns that Iran could try to retaliate after suspected Israeli strikes against the Tiyas or T-4 airbase in February and April. In February, the attack on the Tiyas airbase came after an Iranian drone infiltrated Israel airspace. In April, Israel announced that it was able to determine that the drone had been armed and on an attack mission.

CNN reported last month that United States intelligence had detected cargo shipments from Iran to Syria and feared that the cargo may have been arms with which to attack Israel.

According to the London-based Syrian Observatory for Human Rights at least 15 people were killed in the overnight airstrike, and at least eight of those killed were Iranian personnel.
