Egyptian authorities opened the Rafah border crossing on Monday for two days, officials said. Rafah is the only major crossing between impoverished Gaza, home to 1.8 million Palestinians, and the outside world that does not border Israel, which blockades the strip and allows passage mainly on humanitarian grounds. Egypt shut the crossing in October last year after Islamist militants in Egypt's adjacent Sinai region killed members of its security forces. Since then, it opened the crossing partially and on a few occasions to allow thousands of Palestinians to travel in and out of the Gaza Strip.
