A 68-year-old woman was stabbed to death in her home in Herzliya on Tuesday morning, Hebrew media reported.
MDA paramedics that arrived at the scene confirmed her death upon arrival.
The woman's husband, 70, was arrested on suspicion of committing the murder.
Police have opened an investigation into the incident. They will bring him to a court on Wednesday to extend his arrest.
Reactions to the incident
Chagit Par, chairwoman of the Na'amat women's organization, said in response: "On election day, someone chose to take the life of another woman in Israel. I have every hope that the next government that will be formed, no matter which one, will place the issue of the fight against domestic violence as part of its priorities and not only before elections and as part of campaigns."

"We are shocked at the abominable act. It is unthinkable that a woman would be harmed by an act of violence within the walls of her home," said Herzliya Mayor Moshe Padlon. "The municipality invests heavily in community services designed to respond to any sign of distress within families.
"Unfortunately, the hard data shows that violence against women is a problem that crosses borders, sectors and socio-economic classes - I call on anyone who senses any of the warning signs to immediately contact the Israel Police or the helplines of the municipality."
