What a recently-widowed woman is not allowed to do

She became Muslim after committing zinaa; does she have to wait (‘iddah) before getting married?

Her husband died during her ‘iddah from her final divorce; does she have to observe the ‘iddah of one who has been widowed?

Should she wait out her ‘iddah in the place where her husband died, or go back to her homeland?
