A local official in Lebanon and state media said an Israeli strike Sunday on a southern village killed several family members, with Hezbollah fighters announcing rocket fire in retaliation.
Senior Hezbollah official and member of parliament Hassan Fadlallah said on Thursday that Israel would face reprisal after two sets of strikes on southern Lebanon the previous day killed 10 civilians, half of them children.
A Hezbollah commander, two other fighters and seven civilians were killed in an Israeli strike in south Lebanon's Nabatiyeh, a security source said Thursday, raising the toll from a raid a day earlier.
Lebanon's Iran-backed Hezbollah movement, a Hamas ally, said Thursday it had fired dozens of rockets into northern Israel, a day after Israeli raids killed 15 people including a Hezbollah commander.
