Iran plans to launch drone attacks against Israeli targets from Syrian territory, the United Kingdom-based Syrian Observatory for Human Rights reported on Friday citing Syrian sources working with Iranian militias. Iran has vowed to respond to the killing of Hamas leader Ismail Haniyeh in Tehran earlier this week. According to the report, the attacks are likely to be directed at Israeli targets inside the Israeli-occupied Palestinian territories and Golan Heights. The sources added the Iranian militias will be under orders not to attack United States military bases if Washington does not “participate in repelling the attack on Israel.”
