A man in southern Gaza stabbed his wife to death and seriously injured two of his sons on Tuesday, medics said. The man fatally stabbed his wife following an argument and then stabbed two of his sons as they intervened to protect their mother. He then fled the scene. Najah Abu Shabab, 62, was pronounced dead on arrival at Nasser hospital in Khan Younis, while the sons were treated for their injuries. Hamas police have launched a manhunt to find the perpetrator.
