Israeli intelligence estimates that Hezbollah has brought elements working with it into the Lebanese army, smuggled missiles, and transferred part of its activities underground, with the duration of escalation with Lebanon depending on Hezbollah’s response size, according to Al Hadath reports issued over the past three hours from 3:45 AM to 6:45 AM UTC on December 7, 2025. Al Hadath, citing Israeli intelligence, reported these assessments as breaking news during the three-hour period, highlighting Hezbollah's infiltration of Lebanese military structures and its efforts to conceal operations by moving them underground while smuggling missiles. The estimates also indicate that the length of the current escalation between Israel and Lebanon will be determined by the scale of Hezbollah's forthcoming response, as stated in the third Al Hadath update within the reporting window. These developments occur amid ongoing tensions along the Israel-Lebanon border, with the reports emerging exclusively from Israeli intelligence sources as relayed by Al Hadath.
