Israeli intelligence reportedly shared the new information with U.S. Secretary of State Mike Pompeo, who warned Lebanese Prime Minister Saad Hariri of the secret facility on his state visit to Lebanon in March.
According to an anonymous American source quoted by the report, the missile factory could include the capability of manufacturing precision-guided missiles.
The source said: “We have made it clear to the Lebanese government that Hezbollah is doing something inside Lebanon and that the danger of an escalation with Israel as a result is real”.
In his address to the UN General Assembly in September, Prime Minister Benjamin Netanyahu accused Hezbollah of shielding its massive missile stockpiles behind civilian buildings, including Beirut’s main airport.
The Lebanese terror group’s effort to build accurate and precise missiles, facilitated by Iranian expertise, funding and guidance, has been targeted by Israel on a number of occasions in Syria.
