A strike targeting the Iranian Revolutionary Guards’ Syria spy chief in Damascus and blamed on Israel killed 12 people, a war monitor said in an updated toll, AFP reports.

“The death toll has risen to 12 […] five Iranians, including three IRGC leaders, four Syrians working with the Iranians, two Lebanese, and one Iraqi national,” said the Syrian Observatory for Human Rights of Saturday’s strike.

The British-based monitor with a network of sources inside Syria previously reported 10 deaths.
