Israel launched one of its most intense bombardments against Hezbollah targets in Lebanon this year Thursday, hours after the militant group’s leader condemned deadly twin attacks that he said crossed “all the red lines.

Lebanon and Hezbollah have blamed Israel for the attacks on Tuesday and Wednesday that killed 37 people and wounded around 3,000, although Israel has not directly commented on the attacks, which security sources say were probably carried out by its Mossad spy agency.

Israel has not commented on the mass attack on Hezbollah communications but multiple reports have said it was carried out by its spy agency Mossad.

The Hezbollah leader, Hassan Nasrallah, did not say how his group would respond to attacks on hand-held devices, which killed dozens when pagers and walkie-talkies exploded.
