Israel has described its initial ground incursion into southern Lebanon as “limited,” although its key ally, the Biden administration, has already suggested it could risk dragging on.

Israel says it has launched a ground invasion in southern Lebanon against the armed group Hezbollah, marking another significant escalation of their long-running conflict that has heightened fears of a regional war.

The bombings late Saturday were the latest in a week of stepped up attacks. A bombing on Friday assassinated Hassan Nasrallah, a stunning escalation in Israel’s campaign against the Iranian-backed group.
