Flags flew at half-mast at UN facilities across the globe Monday including at the body's New York headquarters, as staff stood in silent tribute to the more than 100 colleagues killed in Gaza during the Israel-Hamas war.
The blue and white United Nations flag was lowered at 9:30 am local time at offices in Bangkok, Tokyo and Beijing, with other UN venues following suit.
Secretary-General Antonio Guterres led UN personnel in observing a minute of silence at UN headquarters when the clock struck 9:30 am in New York.
"Since the start of this conflict, more than 100 UNRWA staff have lost their lives," he posted on X, formerly Twitter, along with a photograph of senior UN officials somberly standing in silence.
"They will never be forgotten."
The UN agency for supporting Palestinian refugees (UNRWA) said Monday that 102 of its employees had died and 27 had been injured in the Gaza Strip since the war erupted just over a month ago -- the highest number of UN aid workers killed in a conflict in the body's history, according to the agency.
"UNRWA staff in Gaza appreciate the UN lowering the flag around the world," the agency director in the Gaza Strip, Tom White, said in a statement.
"In Gaza however, we have to keep the UN flag flying high as a sign that we are still standing and serving the people of Gaza."
Israel has been relentlessly bombarding the Gaza Strip since Hamas fighters carried out an October 7 attack on southern Israeli communities, the deadliest in the country's history.
About 1,200 people, mostly civilians, were killed in the Hamas attacks and around 240 people taken hostage, according to Israeli officials.
More than 11,000 people, most of them civilians and many of them children, have been killed in Gaza in retaliatory strikes by Israel, according to the territory's Hamas-run health ministry.
- 'Protect civilians' -
In the lobby of UN headquarters, the names of the staffers killed in Gaza were read out as dozens of colleagues listened. Some carried white sheets with the words "Stop the fighting" and "Protect civilians."
In New York and Geneva, the agency's second-largest headquarters, none of the flags of the 193 member countries were hoisted.
"Their memory and the impact they made will forever remain," the head of the UN's World Health Organization, Tedros Adhanom Ghebreyesus, said.
"Their unwavering dedication to peace, justice, and the well-being of others serves as a guiding light and a reminder of the importance of our shared mission."
Events were also held in Kathmandu and Kabul, where the UN Secretary-General's Special Representative for Afghanistan Roza Otunbayeva led about 250 people in observing the minute's silence.
UNRWA, which has 13,000 staff working throughout Gaza, says it is sheltering some 780,000 people in more than 150 facilities in the territory.
On Sunday, a day before the worldwide tribute to fallen staff, the United Nations reported "a significant number of deaths and injuries" in strikes on one of its facilities in Gaza that was housing internally displaced persons.
At least 66 people sheltering in UNWRA facilities have been killed since October 7, according to the mission, with more than 560 people injured.
