When Pope Benedict visited Bethlehem, in the West Bank, last week, he was less than 100 km (60 miles) away from Gaza. But for the 4,000 Christians in this crowded Palestinian territory along the Mediterranean Sea , he might as well have been on the moon. Like nearly all Gazans, they are barred from leaving the Gaza Strip by Israeli restrictions. An Israeli embargo on supplying many essential goods to them has left the impoverished area unable to repair buildings destroyed or damaged by an Israeli offensive in January. Added to all that, the tiny Christian minority has been living since June 2007 under the Islamist rule of Hamas. Faced with conditions like that, attending a papal mass is a luxury few would even dream of.
