Human rights organizations are concerned about the growing number of women executed in Iran, where there is a very high number of executions in 2022.

Many of these women killed abusive husbands, or were married to them as children, human rights advocates note.

According to the NGO Iran Human Rights (IHR), based in Norway, three women convicted of killing their husbands in three separate cases, were executed on Wednesday in different prisons in the Islamic Republic.

In total, at least ten women were hanged in 2022, according to the NGO.

Senobar Jalali, an Afghan national, was executed in a prison near Tehran, according to the same source.

Soheila Abedi, married at the age of 15, was hanged in a prison in the city of Sanandaj (west). She had killed her husband ten years after their marriage and had been sentenced in 2015, said the NGO.

Faranak Beheshti, sentenced five years ago for the murder of her husband, was hanged in a prison in the city of Urmia (north-west), according to the NGO.

According to an October 2021 report by IHR, at least 164 women were executed in Iran between 2010 and October 2021.

Two NGOs, including Amnesty International, denounced on Wednesday an "execution spree" in Iran, where more than 250 people suffered the death penalty in the first six months of the year, "after systematically unfair trials ".

Women do not have the right to unilaterally seek a divorce in Iran, even in situations of domestic violence or abuse, say human rights defenders.
