The Palestinian security establishment has advised American and European citizens to leave the Gaza Strip following kidnapping warnings, Israel Radio reported Wednesday. The warnings were also aimed at United Nations Relief and Works Agency personnel who are in Gaza to aid Palestinian refugees. However, the UNRWA said that they did not intend to pull their workers out of the area. The warning came as searches continued for a French photographer kidnapped in Gaza on Monday. Jaime Razuri, 50, an Agence France Presse photographer from Peru, who was on his way back from an assignment, was kidnapped at gunpoint in Gaza City as he got out of his car with his driver. Razuri was the latest in a string of foreigner kidnappings that have become prevalent in Gaza. Over the summer, two Fox News employees were held for two weeks. Most of the kidnapped foreigners have been journalists, but aid workers have also been targets. News agencies contributed to this report.
