Israel has neither confirmed nor denied that it killed Saleh al-Arouri in a drone strike in the Lebanese capital on Tuesday. But military spokesperson Rear Admiral Daniel Hagari said Israeli forces were in a high state of readiness and prepared for any scenario.

The assassination was a further sign that the nearly three-month war between Israel and Hamas was spreading across the region, drawing in the occupied West Bank, Hezbollah forces on the Lebanon-Israel border, and even Red Sea shipping lanes.
