Israeli airstrikes in Lebanon have intensified following a period of relatively low activity after a ceasefire began on April 17. The scope of Israel Defense Forces (IDF) airstrikes gradually increased, peaking on May 2, with a renewed surge on May 6. This escalation coincided with Hezbollah reportedly increasing the scale of its attacks against Israel and against IDF forces operating in Lebanon. On May 3, Hezbollah carried out 12 attacks, and on May 5, the group conducted a peak of 20 attacks in a single day. On May 6, an IDF airstrike in the Haret Hreik neighborhood of Beirut’s Dahieh eliminated Ahmad Ghaleb Ballout, a commander in Hezbollah’s Radwan Unit, marking the first such strike in Beirut since the ceasefire began.
Shifting Strike Patterns
The majority of Israel Defense Forces (IDF) activity was concentrated south of the Litani River from the beginning of the ceasefire, according to reports. However, several significant increases in IDF airstrikes north of the Litani were recorded, particularly in early May and again on May 6. Most IDF airstrikes were conducted outside the "Yellow Line," a term the IDF reportedly used for the first time in Lebanon, having previously applied it to a line in Gaza. The number of IDF airstrikes inside the "Yellow Line" remained relatively low and stable throughout the period, reports indicated.
More than two weeks ago, during ground operations in southern Lebanon, multiple brigade combat teams under four division commands deployed along what the General Staff defined as the "Yellow Line." This temporary line connects key terrain to prevent direct fire on border communities. On Saturday, the IDF stated that troops operating south of the "Yellow Line" identified terrorists who violated ceasefire understandings and approached from the north in a way that posed an immediate threat. The IDF also reported striking terrorists in southern Lebanon, including eliminating a terrorist cell operating near troops in what it described as a forward defense line aimed at preventing direct threats to northern communities. Additionally, the IDF struck an underground shaft south of the line and Hezbollah terrorists identified entering it, alongside striking suspects in several locations in southern Lebanon.
Defining the 'Yellow Line'
Following U.S. President Donald Trump's announcement of a ceasefire in Lebanon and his statement that Israel should halt strikes there, a "yellow line" has effectively been established where Israel Defense Forces (IDF) remain deployed. Military officials stated that the IDF’s defensive layout in the area is divided into three lines: the red line, the yellow line, and the Litani line.
The red line delineates villages near the border, many of which have sustained heavy damage. The yellow line functions as an anti-tank defense where forces are currently positioned to prevent direct fire toward northern communities. The third line runs along the Litani River, which the IDF maintains under fire control. In some areas, troops are positioned approximately 10 kilometers (6 miles) from the border.
The IDF has defined a new line up to which it maintains control, referring to it as the anti-tank line captured during ground operations in southern Lebanon. This line begins in the east near a bend in the Litani River, around the town of al-Khiam northeast of Metula. It then passes through Taybeh near the river and Bint Jbeil, continuing along a ridge before concluding in the west near Ras al-Naqoura. This area includes 55 Lebanese villages whose residents are not permitted to return.
IDF Operational Directives
The data presented refers solely to Israel Defense Forces (IDF) airstrikes and does not include ground operations, artillery fire, or other military activity. Forces have standing orders to act immediately to remove any threat wherever it is identified, according to military officials. During the ceasefire, the IDF continues to clear what it describes as Hezbollah terrorist infrastructure within this zone, effectively treating it as a security buffer. The military called on terrorists believed to remain in the area, including in Bint Jbeil, to surrender, stating they will be targeted once located if they do not. The Israeli Air Force continues to operate over southern Lebanon to neutralize threats as needed. Artillery fire was used to support ground forces, and terrorist infrastructure was destroyed in response to threats, the military added. The IDF emphasized it is operating under directives from the political leadership but retains the authority to act in self-defense. Actions to remove threats and protect forces are not restricted by the ceasefire, and the IDF will take all necessary measures to ensure the safety of Israeli civilians and troops. During a recent cabinet call, Prime Minister Benjamin Netanyahu updated ministers on the yellow line, noting that Donald Trump is pushing to advance a ceasefire but that Israel must maintain freedom of action along the line.
