Radical Salafist sheikh Ahmad al-Assir had made an arm storage filled with different types of ammunition at the Bilal Bin Rabah Mosque which he had declared himself to be its Imam.
A video, released by Almanar, shows the mosque filled a considerable amount of arms packed and stored under the building.
The army took control over the mosque after two days of heavy clashes which started on Sunday fallowing Assirâ€™s followersâ€™ attack on a Lebanese army checkpoint in Sidon.
At least 17 soldiers and over 40 gunmen were killed in clashes.
The wounded included nearly 100 troops, 60 Assir supporters and over 50 civilians.
