Swedish security officials are investigating Israeli death threats directed at their foreign minister Margot Wallström.

Last week, Zvi Zameret, a former official of Israel’s education ministry, published an article in Hebrew implying that Wallström deserved the same fate as Count Folke Bernadotte, a Swedish UN diplomat murdered by a Zionist militia in 1948.

“There are security people looking at this issue and we have no more comment than that,” Wallström’s spokesperson Kristian Brangenfeldt told the Swedish publication Etc.

“But I know which article you mean,” Brangenfeldt added in reference to Zameret’s op-ed, “and it felt very strange.”

Wallström has raised the ire of Israeli Prime Minister Benjamin Netanyahu for suggesting that there should be an investigation into Israel’s frequent killings of Palestinian youths that human rights groups term extrajudicial executions.

The Israeli leader recently denounced Wallström’s comments as “outrageous and stupid.”

Wallström also angered the Israelis by connecting the kind of radicalization behind the November attacks in Paris that killed 130 people to the situation in the Middle East, “where not least, the Palestinians see that there is not a future.”

Sweden was already in Israel’s bad books for announcing in 2014 that it would recognize the “State of Palestine”. Earlier this month, Wallström cancelled a visit to Israel after officials said they would refuse to meet her.
