What Nasrallah Said About Israel's Actions
Hezbollah's leader said the movement views Israel's actions as crossing all red lines.
Nasrallah also called Israel's actions a terrorist operation and a deliberate massacre.
In relation to the Lebanese state, this means a de facto declaration of war, he said.
