A Fiji national is among three UN workers killed in a car bombing outside a shopping mall in Libya yesterday.
The workers were part of the United Nations Support Mission in the country.
Seniloli Tabuatausole, a former soldier with the Republic of Fiji Military Force, has been named as one of the dead.
Fiji Prime Minister Frank Bainimarama, who is attending the Pacific Island Leaders meeting in Tuvalu, said his nation's outsized role at the UN sometimes came with outsized sacrifices.
The UN condemned the attack but said it would not evacuate its staff from Libya.
The Security Council convened an emergency session in New York to discuss the latest developments in Libya.
"We mourn the death of one of our own who was senselessly killed by a car bomb in Libya," Mr Bainimarama tweeted.
"I send my condolences to the family of the fallen."
Sadly, Fiji's outsized role at the @UN sometimes comes with outsized sacrifice. Today, we mourn the death of one of our own, who was senselessly killed by a car bomb in Libya. I send my condolences to the family of the fallen. God bless Fiji, and God bless our peacekeepers. pic.twitter.com/KFWQsxBuR3— Frank Bainimarama (@FijiPM) August 11, 2019
UN Secretary-General Antonio Guterres called on the Libyan authorities to spare no effort in identifying and swiftly bringing to justice the perpetrators of the attack.
"Calls on all parties to respect the humanitarian truce during Eid al Adha and return to the negotiating table to pursue the peaceful future the people of Libya deserve," he said in a statement.
The UN said three other staff members and dozens of civilians were injured in the attack.
