Nearly 1 million women in Iraq are widows or divorcees, or their husbands are missing, according to Samira al-Mosawi, a Shiite member of parliament who heads the women’s affairs committee. . . . Mosawi said approximately 86,000 widows are receiving about $40 a month from the government. Aid organizations and government agencies are unable to help more widows because of a lack of funds and the challenges of doing social work in volatile neighborhoods.
