Israel sent 29 Palestinian prisoners back to the Gaza Strip on Tuesday, completing a release meant as a goodwill gesture ahead of a U.S.-sponsored Mideast peace conference this fall. The release of the Gaza prisoners was held up for a day after Israel's military chief expressed reservations over the move. In the first stage of the release, Israel freed 57 prisoners to the West Bank on Monday. The Gaza prisoners walked through the terminal at the Erez border crossing and were greeted by a large crowd of relatives, the Associated Press reported.
