BEIRUT: Hezbollah’s chief said Tuesday his group and Iran were “obliged to respond” to Israel “whatever the consequences” after the killings last week of Hezbollah military commander Fuad Shukr and Hamas leader Ismail Haniyeh. The twin killings have sent Middle East tensions skyrocketing, amid fears of a regional conflict and all-out war between Israel and Hezbollah, which have been trading daily cross-border fire since Palestinian militant group Hamas’s October 7 attack on Israel.
