Israel and Hezbollah exchanged missile strikes on Tuesday morning, following the deadliest day in Lebanon since 2006.

Lebanese officials reported that a large-scale Israeli bombardment killed at least 560 people on Monday, prompting thousands to flee southern Lebanon. Hezbollah, an Iranian-backed militant group, remains on the verge of a full-scale war.

Hezbollah claimed it launched missiles at eight different targets in Israel early Tuesday. The Israeli military confirmed tracking 55 rockets fired from Lebanon and landing in Israel.

Israeli forces stated they have continued to target Hezbollah positions within Lebanon, employing artillery and tanks to strike targets near the border.

Israel said it is targeting Hezbollah cells and weapons caches throughout the country.

Data from American fire-tracking satellites analyzed by The Associated Press on Tuesday revealed the widespread nature of Israeli airstrikes in southern Lebanon, covering an area exceeding 650 square miles. 

These satellites, part of NASA’s Fire Information for Resource Management System, are typically used to monitor wildfires in rural areas of the United States, but can also detect the flashes and burning that follow airstrikes. This is particularly true when an airstrike ignites flammable material on the ground, such as munitions or fuel.

Top Israeli officials insist they do not seek an escalation of the conflict with Hezbollah into a full-scale war. Israeli President Isaac Herzog stated on Sunday that the concentration of weapons and equipment at the Israel-Lebanon border is not a preparation for an invasion.

Defense Secretary Lloyd Austin held consecutive calls with Israeli Defense Minister Yoav Gallant over the weekend, urging a ceasefire and a de-escalation of tensions in the region.

“Given the tensions, given the escalation, as I highlighted, there is the potential for a wider regional conflict. I don’t think we’re there yet, but it’s a dangerous situation,” Maj. Gen. Pat Ryder said on Monday.
