BEIRUT, Lebanon, Aug. 15 (UPI) -- Hezbollah leader Sheikh Naim Qassem issued a strong warning to the Lebanese government against moving forward with its plan to disarm the Iran-backed militant group, accusing it of acting on orders from the United States and Israel, and threatening that such a move could spark a civil war.

Qassem said his group will not "surrender its weapons" while Israel, which significantly weakened Hezbollah during a 14-month war last year, remains a threat and continues to strike Lebanon, occupy parts of its territories and hold Lebanese prisoners.

"We will fight this as a Karbala-style battle if necessary, confronting this Israeli-American scheme no matter the cost, confident that we will emerge victorious," he said in a televised speech released Friday.

To Muslim Shiites, Karbala means standing against tyranny, sacrifice and steadfastness in the face of overwhelming odds.

Qassem's strong warning came after he met with Iran Supreme National Security Council Secretary Ali Larijani, who visited Beirut on Wednesday, where he heard firm statements from President Joseph Aoun and Prime Minister Nawaf Salam rejecting any interference in their country's internal affairs.
