International journalists based in Israel were appealing to the country's Supreme Court to overturn a government decision banning journalists from entering the Gaza Strip. The Foreign Press Association filed the court petition after a letter signed by heads of the world's biggest news organizations and sent to Israel's premier failed to persuade the government to lift the ban. Israel has long restricted movement across its border with Gaza, but after a recent upsurge in Palestinian rocket fire, it closed the strip off to all but the most vital supplies. The only people allowed in or out are urgent medical cases and a handful of humanitarian workers. Journalists have been barred since Nov. 5. The court petition filed Monday asks for an urgent hearing over the case.
