Deadly Israeli attacks that blew up Hezbollah radios and pagers crossed all red lines, the leader of the heavily armed Iran-backed Lebanese movement said on Thursday, as the United States called for restraint and urgent de-escalation.

The strikes aim to "degrade Hezbollah’s terrorist capabilities and infrastructure," the IDF said in a statement.

Jets were reported flying over Beirut during a speech by Hezbollah leader Sayyed Hassan Nasrallah, causing panic among Lebanese residents already tense from recent blasts attributed to Israel.
