Northern Ireland politician Gerry Adams ×on Wednesday called on Israel and the Palestinians to stop fighting and negotiate an end to their decades-old conflict. The Sinn Fein leader arrived in the Gaza Strip on Wednesday as part of a visit to Israel, Gaza and the Palestinian Authority. Adams discouraged comparisons between Ireland and the Middle East but said his experience in the Northern Ireland peace process proves that "dialogue works." Officials had said Tuesday that Adams would not be allowed into Gaza, becuase he planned to meet with Hamas officials. It was not clear why Israeli officials changed their mind.
