Jean-Pierre Lacroix, under-secretary-general for peace operations, said Monday that all three peacekeepers who were killed were from the Indonesian army. That makes 97 fatalities of UNIFIL peacekeepers due to malicious acts since the mission began in March 1978 and a total of more than 330 fatalities — the most of any U.N. peacekeeping operation.
