The badly bruised body of a woman in her 20s was found on the floor of her family home in the Western Galilee village of Yarka on Sunday, and her husband was arrested on suspicion of murdering her.
An MDA team pronounced the woman dead at the scene in the Druse village.
Police arrested the 30-year-old husband and he was being interrogated at the Acre Police Station.
However, the circumstances of the woman's death were still unclear, and police said it didn't appear that the couple had a history of violence.
In another apparent murder, 63-year-old Taibe woman Sabra Haj Yihya was found shot dead at the entrance to her home overnight Saturday.
Police said from the initial inquiry it appeared that after hearing a knock at her door, the woman peeped out of her window and was shot multiple times with an automatic weapon.
Following the murder, police found a torched car in northern Taibe that they suspect was used by the attackers. The motive for the shooting was unclear.
