Israel and Hezbollah have been at war for decades, but the conflict escalated quickly in recent weeks, after a rocket killed more than 10 people in the Israeli-controlled Golan Heights last month. Hezbollah said in early July that if Israel and Hamas come to a cease-fire agreement, it would stop fighting. Israel hit Hezbollah targets in Lebanon in what it called a preemptive strike to stop an imminent attack by the militant group, and Hezbollah followed up with hundreds of rockets, a major exchange between the two that came as fears of escalation in the Middle East increase—and negotiators work toward a delicate Israel-Hamas cease-fire. Is the Israel war starting to spread across middle east ?
