Calls grow louder to extend a fragile pause in fighting and allow more aid into Gaza.
After weeks of intense Israeli bombardment, a humanitarian truce is being used to exchange dozens of detainees and captives between Israel and Hamas.
But that deal hit a snag on Saturday, when a disagreement led to several hours of delay in releasing captives.

And what are the logistical implications of facilitating such an agreement?
Can it be extended beyond the four days agreed upon?
