PA reports that there are 187 Palestinian "veteran prisoners" in Israeli prisons
“Yesterday, Thursday [April 21, 2022], prisoners Abd Al-Majid Mahdi (i.e., terrorist, murdered 1) and Ziyad Hamoudeh (i.e., terrorist, participated in the murder of 2), both from the Ramallah and El-Bireh district, began [their] 21st year in the occupation’s prisons, and thus joined the list of most veteran prisoners that rose today to 187 prisoners.
The [PLO] Commission [of Prisoners’ Affairs] explained in a press release that the occupation army arrested prisoner Mahdi on April 21, 2002, and sentenced him to life, and it arrested prisoner Hamoudeh on the same day and sentenced him to 23 years.
It added: ‘Among “the most veteran prisoners” there are 25 prisoners who were arrested before the  Oslo [Accords]… including 13 prisoners who have served more than 30 consecutive years, the most veteran of whom are prisoners Karim and Maher Younes (i.e., terrorist cousins who murdered 1), who have been imprisoned since January 1983.’”
