Israeli Prime Minister Benjamin Netanyahu warned Syrias head of regime Bashar al-Assad, during a visit to London on Thursday, saying his regime is “no longer immune” from retaliation. “He is no longer immune, his regime is no longer immune. If he fires at us, we will destroy his forces,” Netanyahu said. “I think there is a new calculus that has to take place and Syria has to understand that Israel will not tolerate the Iranian military entrenchment in Syria against Israel,” he added while speaking at an event organized by the Policy Exchange think tank. According to AFP, "Israel has been pledging for months to prevent its main enemy Iran from entrenching itself militarily in Syria, where Tehran is backing Assads regime." Back in May, Israel launched a large-scale attack on what it said were Iranian targets in Syria. Israel had been blamed for a series of recent strikes inside Syria that killed Iranians, though it has not acknowledged them, AFP reported.
