History of International Day of Solidarity with Detained and Missing Staff Members
The day is marked on 25 March, the anniversary of the 1985 abduction of Alec Collett, a journalist working on assignment for UNRWA near Beirut. His remains were found in Lebanon in 2009.
The UN General Assembly adopted the Convention on the Safety of United Nations and Associated Personnel on 9 December 1994 through resolution A/RES/49/59. The convention is a major part of the protection framework discussed alongside the observance.
UN material continues to use 25 March as the annual date and describes the day as a moment to mobilize action, demand justice and strengthen protection for staff, peacekeepers and other colleagues at risk.
