There are further signs of growing pressure on Hamas after it took control of Gaza. An Israeli energy company says it has cut back fuel supplies to the territory. Dor Alon says fuel is still being provided for Gaza power stations, but not for smaller petrol stations.
The Israel government has also said it wants to isolate the territory, allowing nothing to get through there except water and power.
Hamas has been insisting it can restore security and keep essential services going in Gaza.
What is clear, however, is that many people are having to rely on foreign humanitarian aid.
While Western governments have backed President Abbas, they have promised to maintain flows of food and medical aid.
Many Palestinians have been trying to flee Gaza amid the growing political uncertainty.
