Palestinian teenager Ahed Tamimi could be released on Sunday, her father told the Anadolu Agency.
Basem Tamimi said Ahed's release is scheduled for 19 August but he expects her to be allowed out of Israeli jail this weekend.
"The Israeli authorities usually do not inform the detainee or his family of the date of his release, but I think she will get a decision" to reduce her detention by 21 days, he explained.
There was no information from the Israeli prison authorities on Ahed's release.
Ahed was given an eight month jail terms following a pleas bargain after video footage of her slapping an Israeli occupation soldier and forcing him off her family's property went viral on social media. She has been held in Israeli detention since her capture in December last year.
