Hezbollah has accused Israel of crossing “all red lines” with its deadly detonation of walkie-talkies and pagers, as Israeli forces launched a fresh wave of strikes across Lebanon. Sonic booms from low-flying Israeli jets shook the buildings in Beirut during a televised speech by the militant group’s leader Hassan Nasrallah in which he warned this week’s unprecedented action “could be called a declaration of war”.

Hassan Nasrallah refused to say when or how Hezbollah would take revenge. As he spoke, Israeli fighter jets swooped low over Beirut.
