World IN BRIEF : EGYPT : Police Seek Gunmen Who Killed Tourists

Police searched near the Pyramids of Giza and set up roadblocks, seeking gunmen who killed 18 Greek tourists in what could have been a case of mistaken identity. Police said they were investigating whether the gunmen mistook the Greeks for Israelis. No one has claimed responsibility for the attack. In a possibly related incident, three suspected Muslim rebels seized a pickup truck in rural Egypt and killed its driver. A map of Giza was found in the abandoned vehicle. Officials said they believed the hijackers were members of Gamaa al Islamiya, which has been blamed for most of the violence in a four-year effort to overthrow Egypt’s secular government.
