An Afghan prisoner murdered his wife when she went to visit him, allegedly because she had been unfaithful after he was jailed for killing her relatives, police said.
Din Mohammad was sentenced to 20 years in prison two years ago for killing his mother-in-law, and his wife's brother and sister in the northern province of Samangan.
Mohammad's wife, whose name has not been disclosed, visited him in jail in the provincial capital Aybak on Monday and was found dead in a small private room used for inmates to see their wives, police said.
Mohammad confessed to her murder, Samangan police chief Ikram Nikzad told AFP.
"Mohammad was told by his mother that his wife had affairs," he said, citing a police investigation.
