In exchange for captured IDF soldier Gilad Schalit, Israel has agreed to free all Palestinian prisoners demanded by Hamas, apart from four, according to two "credible" Palestinian sources quoted by Al-Quds al-Arabi on Monday. The four are: Abbas el-Sayid - Hamas's Tulkarm commander convicted of planning the 2002 Pessah suicide bombing at Netanya's Park Hotel; Abdullah Barghouti - behind numerous terror attacks including suicide bombings at Jerusalem's Sbaro restaurant and Moment café; Ibrahim Hamed - who planned attacks including bombings at the capital's Hebrew University and Zion Square; and Ahmed Sadat - secretary-general of the Popular Front for the Liberation of Palestine, who is suspected of involvement in the murder of tourism minister Rehavam Ze'evi in 2001. The London-based newspaper said that Turkish mediators promised Hamas to try and convince Israel to release the four.
