Four Katyusha rockets were fired from Lebanon at northern Israel on Monday night, causing damage to buildings and igniting a blaze that firefighters fought for hours. One of the 22-millimeter rockets struck a gas tank. No casualties were reported. The Israel Defense Forces responded to the rockets by firing artillery rounds. Police and IDF forces scanned the area in search of more rockets and were able to confirm that four rockets had struck. The IDF called the incident serious and said it holds the Lebanese government responsible for stopping rocket fire. Israel's security services do not believe Hezbollah is responsible for the overnight attack, but blame a smaller faction instead, likely to be linked to the global jihad movement. Those operating with the global jihad in southern Lebanon are known to be Palestinians. This is the first disturbance of its type in almost two years and the eighth since the cease fire ended the Second Lebanon War. So far, one Israeli has been wounded in these incidents. The United Nations International Force in Lebanon vowed Tuesday morning to ensure that the border remain calm, and UNIFIL commanders held emergency meetings with representatives of the Israel Defense Forces and the Lebanese Army following the overnight attack.
