RAFAH, Egypt, July 2 (Reuters) - Dozens of Palestinians pelted Egyptian border police with stones at Egypt's border with the Hamas-held Gaza Strip on Wednesday, in an attempt to force their way into the Sinai peninsula, witnesses said.

Live television footage showed Egyptian forces responding with water cannon and sealing the gates to the crossing point.

Hundreds of thousands of Palestinians stormed the border crossing in January to stock up on much needed supplies to get around an Israeli-led blockade of the Gaza Strip. (Reporting by Mohamed Yousef, writing by Aziz El-Kaissouni)
