Prime Minister Ehud Olmert has promised to free 250 Palestinian prisoners next month, Israeli and Palestinian officials said Monday. The move would be the latest in a series of prisoner releases meant as goodwill gestures to Palestinian Authority President Mahmoud Abbas. Negotiator Saeb Erekat said Olmert informed Abbas of the planned release during a meeting in Jerusalem. Olmert spokesman David Baker confirmed the release, but said a date had not yet been set. The gesture is meant to coincide with an upcoming Muslim holiday.
