A Palestinian man exchanges Egyptian currency in Rafah, on the border between the Gaza Strip and Egypt, after Hamas militants destroyed the border wall between Gaza and Egypt, 23 January 2008 at Rafah refugee camp, southern Gaza. Thousands of Gazans poured into Egypt today after militants set off at least five explosions along the walled-off border of the Hamas-ruled Gaza Strip, witnesses said. The forced entry came as Israel imposes a months-long blockade of the impoverished territory that was tightened last week to a full-scale lockdown. Crowds of Palestinians walked the streets of Rafah as shops opened early to serve them. Photo by Abed Rahim Khatib /Flash90
