Police on Saturday arrested 33 students affiliated with Egypt's largest opposition group, the outlawed Muslim Brotherhood, who were spending their summer vacation in the Mediterranean Sea city of Alexandria, a police official said. Authorities allege the students were reviving the banned group's activities while at el-Agamy beach resort, said the official, speaking on condition of anonymity because he was not authorized to speak to the press. The Brotherhood's official Web site said 35 students were arrested. It was not immediately known why there was a discrepancy in the number of arrested students. "The gathering was for a group of young men, and the security forces didn't find any outlawed documents with them," a statement posted on the group's site said.
