Palestinian president Mahmud Abbas has warned of action if Israel fails to release the fourth and final batch of veteran prisoners as agreed under a US-backed deal.
"We are awaiting the release of the fourth batch of prisoners, as agreed upon with the Israelis through the United States," he told members of the central committee of his Fatah movement.
"We are saying, if they are not released, this is a violation of the agreement and allows us to act however we see fit within the norms of international agreements."
Israel agreed to release a total of 104 long-term prisoners when talks kick-started by US Secretary of State John Kerry began in July.
It has freed 78 so far, nearly all of them who had been imprisoned for mnore than 20 years.
