Israel struck Beirut's southern suburbs on Sunday, killing three people, in response to what it said was Hezbollah fire at northern Israel, while its military also carried out broader strikes on southern Lebanon.
The latest escalation came amid expectations that a deal between the United States and Iran to end the Middle East war could be imminent, but Iranian chief negotiator Mohammad Bagher Ghalibaf said there was "no point" in continuing peace talks with Washington after the strike.
Tehran insists a ceasefire in Lebanon must be part of any deal.
