At least 21 foreign fighters were killed in Israeli strikes on Syria this week, according to the Britain-based Syrian Observatory for Human Rights.
"At least 27 pro-regime fighters were killed" in Thursday's strikes, director of the Observatory for Human Rights Rami Abdel Rahman said.
He said that "six Syrian soldiers and 21 foreign fighters, including 11 Iranians" were among the dead. That updates the monitor's initial toll of 23, which did not specify the number of Iranians, AFP reported.
"The new report is due to the death of wounded or missing persons whose deaths have been confirmed," Abdel Rahman added.
Israel says it struck dozens of Iranian targets inside Syria early on Thursday in response to a salvo of rockets allegedly fired by Iranian forces into the Israeli-occupied Golan Heights.
