BEIRUT, Lebanon: A Syria war monitor said early Monday that Israeli strikes had targeted military sites in Syria’s coastal Tartus region, calling them “the heaviest strikes” in the area in more than a decade. “Israeli warplanes launched strikes” targeting a series of sites including air defense units and “surface-to-surface missile depots,” said the Syrian Observatory for Human Rights, in what it said were “the heaviest strikes in Syria’s coastal region since the start of strikes in 2012.”
