“Yes, we were subjected to a huge and severe blow,” Nasrallah said. “The enemy crossed all boundaries and red lines,” he added.
As usual, Nasrallah spoke by video from an undisclosed location. Hezbollah typically convenes a rally for supporters to watch his speeches on a big screen, but this time they did not.
