RAMALLAH, May 22 (Xinhua) -- The Palestinian National Authority (PNA) said on Tuesday that Israel has violated an Egypt-brokered prisoner deal that demands the transfer of 18 Palestinians it jailed from solitary confinement to regular cells.

Palestinian Minister of Prisoners Affairs Eissa Qaraqe' said Israel is still holding one prisoner in solitary confinement, pointing to its "intention to evade the articles of the agreement. "

Egypt brokered the deal 28 days after the prisoners started hunger strike against their detaining conditions. The jailed Palestinians only ended the hunger strike last week.

Qaraqe' said the prisoner still held in solitary confinement was a Gazan power plant director called Dirar Abu Sisi. He was kidnapped by Israel during his trip to Ukraine. Israel transferred him to its own territory in February 2010.
