Over a hundred Palestinians from Gaza were unable to obtain permits to participate in the "Palestine Marathon" after submitting their requests too late, AFP reports.
Among the Gazans prevented from traveling ahead of Friday's marathon in Judea and Samaria was reigning champion and Olympian Nader al-Masri.
COGAT, the IDF body responsible for implementing government policies for Palestinians in Judea and Samaria, said the forms for 102 runners from Gaza were "submitted in too short notice and given a timeframe which is not the adequate amount of time for dealing with such requests."
The marathon takes place on Friday and will see thousands of people start running from near the Church of the Nativity in Bethlehem.
The Gisha NGO, which campaigns for freedom of movement for Palestinians, said civilians had been caught in an administrative dispute.
"We are disappointed, if not surprised, to hear that civilians in Gaza are again paying the price for the apparent negligence and disregard of both Israeli and Palestinian officials," a statement said.
