Israel’s apparent ability to infiltrate global supply chains has sent ripples of fear through Iran’s network of armed groups across the Middle East.

Israel is believed to have conducted a series of clandestine attacks on adversaries linked to Iran in recent years, sometimes using highly innovative tactics.

Sen. John Fetterman (D-Pa.) says on Meet the Press that he “absolutely” supports the new wave of attacks against Hezbollah, which are widely believed to be conducted by Israel, including the device blasts in Lebanon.

Hezbollah fired more than 100 rockets, drones and missiles into Israeli territory on Sunday morning. The attack came in response to strikes on militia members in Lebanon last week.

The Lebanese militant group launched around 150 missiles, rockets and drones into northern Israel overnight into Sunday morning.

Sunday opened with a new barrage of Hezbollah fire into northern Israel, per the Israel Defense Forces, which continued its own campaign of cross-border strikes.
