Via Maya Gebeily, Tom Perry and James Mackenzie in reuters.com: Israel struck Hezbollah targets in southern Lebanon and its Iran-backed foe attacked military facilities in northern Israel on Tuesday, increasing fears of a full-blown conflict after Lebanon suffered its deadliest day in decades. Israels military said it hit dozens of Hezbollah targets overnight, a day after carrying out airstrikes against the armed group which Lebanese authorities said killed 558 people, including 50 children and 94 women, and wounded 1,835. Tens of thousands more have fled for safety.
