Israel carried out airstrikes on southern Lebanon early Thursday, hours after the militant group Hezbollah fired rockets into Israel following a deadly border clash. The Israeli military said it targeted Hezbollah positions in response to the rocket attacks, which caused no reported injuries or damage. Hezbollah claimed responsibility for the rocket fire, saying it was retaliation for an Israeli airstrike that killed two of its members and wounded seven others near the border. The clashes marked the most serious escalation between the longtime enemies since the 2006 Lebanon War.
