Eunice Abdallah’s brother, Mohamed, was killed by Islamic State (IS) militants a few days after her husband, Mohamed, told her he was leaving for Turkey.
Mohamed was killed in IS’s latest beheading video, which showed the beheading of US journalist Steven Sotloff.
The Sotloff killing caused international outrage, with more than 170 nations taking part in a formal condemnation.
The video shows two IS militants standing next to one another in an orange jumpsuit with a sword and a hooded head-dress.
The video then shows the militants standing with arms extended at a black “crucifixion site”, apparently referring to the execution location at Abu Ghraib prison in Iraq during US occupation.
The militants then begin to parade around with an Islamic flag at their side while a captive woman in black clothes, which could be the woman in the video, is tied behind her.
Mohamed says “allahu Akbar” – which means “God is great” – and waves the arms in a prayer.
The executioner appears wearing a black hood, but some footage on the Sotloff video shows only a white bandana.
The executions of Sotloff and al-Jumaili were the latest in a series of IS executions in Libya.
Hundreds of IS fighters from Libya have been killed in recent months as Tripoli’s rival armed groups battle for control of Libya’s east.
A video of the beheading of a Japanese man by masked IS militants released on Facebook last week prompted a global outcry and a call for calm, but not any further IS executions until Libya’s army can be properly trained.
The footage shows a masked man kneeling before the flag-waving IS militants holding up a knife or machete.
The masked man says he is Mohammed Emwazi, a British-Libyan convicted last week in the US to terrorism charges after being named as the mastermind behind the November 13 attack on the Paris offices of weekly satirical newspaper Charlie Hebdo, which left 17 killed.
The British-born Emwazi, 25, is thought to still be in Libya, the same country in which he was sentenced to death a year and a half ago by a court in the western Libyan town of Tobruk.
