Lebanon and Israel have repeatedly traded strikes since the Gaza war began in October, killing civilians and combatants in Lebanon and Israel. For months, concerns have grown that the war in Gaza might ignite a second conflict between Israel and Hezbollah, the well-armed militia that is loosely allied with Hamas and based just across Israel's northern border with Lebanon. The two sides have repeatedly traded strikes since the Gaza war began in October, killing civilians and combatants in Lebanon and Israel, with most of the civilian casualties in Lebanon. The hostilities have also forced more than 150,000 people on both sides of the border to leave their homes for temporary shelters. That has put pressure on the Israeli government to make the north of the country safe for residents again by pushing Hezbollah back from the border region.
