The Internal Security Forces are the national police and gendarmerie of Lebanon.
Modern police were established in Lebanon in 1861, with the creation of a gendarmerie force. In April 2005, Ashraf Rifi became head of the ISF, replacing Ali Al Hajj. Rifi then started to recruit younger members to become part of Lebanese Intelligence. His term ended in April 2013, and he was replaced by Roger Salem, and Ibrahim Basbouss subsequently. On March 8, 2017, the Lebanese Cabinet appointed Imad Othman as the ISF director general. He took command the following day.
The number of ISF personnel reached 100,000 by 2000 and grew to over 131,000 by 2013. The ISF National Day in Lebanon is on the 9th of June.
