The 2013 Lahad Datu standoff, also known as the Lahad Datu incursion or Operation Daulat (Operasi Daulat), was a military conflict that started on 11 February 2013 and fully ended on 24 March 2013. The conflict began when 235 militants, some of whom were armed, arrived by boats in Lahad Datu District, Sabah, Malaysia from Simunul island, Tawi-Tawi, in southern Philippines. The group, calling themselves the "Royal Security Forces of the Sultanate of Sulu and North Borneo", was sent by Jamalul Kiram III, one of the claimants to the throne of the Sultanate of Sulu.
