Many are left destitute – robbed of their inheritance – while others are enslaved by their in-laws, accused of witchcraft or forced into abusive sexual rituals, Reuters said.

International Widows' Day on June 23 aims to raise awareness of the often hidden injustices faced by widows.

Here are some facts:

- There are an estimated 258.5 million widows globally with 584.6 million offspring.

- Deaths through conflict and disease contributed to a 9 percent rise in the number of widows between 2010 and 2015.

- The biggest jump has been in the Middle East and North Africa, where the estimated number of widows rose 24 percent between 2010 and 2015, partly due to the Syrian war and other conflicts.

- One in seven widows globally – 38 million – lives in extreme poverty.

- Widow "cleansing" rituals in some sub-Saharan countries may require a widow to drink the water used to wash her dead husband's body or to have sex with an in-law or a stranger.

- Campaigners for widows' rights say such rituals, which are intended to rid a widow of her husband's spirit, spread disease and are a violation of dignity.
