Hezbollah leader Hassan Nasrallah called the attack on Avivim a success on Monday night, which was "deliberately" carried out during the day.“Israel, the tyrant and arrogant, claiming to possess the region’s strongest army, was seen by the world scared and worried for 8 days," he said during a speech. Hezbollah, he said, broke "the biggest red line for dozens of years" for Israel by targeting it across border, not in the contested Shebaa farms area where the group had previously targeted IDF troops.The attack against Avivim was a message to Israel, Nasrallah warned. "We no longer have red lines. This is the start of a new phase. Remember this date."The IDF’s Northern Command has been on high alert since last week, expecting a limited strike against military targets over strikes in Syria and an alleged Israeli drone attack in Beirut’s Dahiyeh last week.While Israel has remained quiet and not claimed the attack in Beirut, Nasrallah said the Israeli attack "was a failure."In a televised speech, Nasrallah said the new focus, now in the hands of fighters in the field, would be on targeting Israeli drones entering Lebanon's skies.He said Hezbollah's Sunday attack had sent Israel a message that "if you attack, then all your border, your forces and your settlements" will be at risk.Reuters contributed to this report.
