Israel says it is attacking Hezbollah in Lebanon

Israel said it was attacking Hezbollah after claiming the group fired 30 rockets into northern Israel from Lebanon. 

"Approximately 30 launches were identified from Lebanon toward northern Israel over the last hour," the Israeli army said. 

"The IDF is responding with artillery fire toward the origin of the launches."

The Israeli army's statement comes after an earlier Israeli strike in southern Lebanon killed three children and their grandmother.
