Kassel (Germany) - A Ghanaian man stabbed his wife to death after she cut off his penis with a breadknife, police in the central German city of Kessel said.

The 50-year-old woman died of her injuries in hospital after her husband, a 37-year-old man of Ghanaian origin, stabbed her during a domestic dispute on Wednesday.

The woman had previously sliced off her husband's penis during the fight.
