A money dispute between the rival Palestinian governments is threatening to shut down Gaza's only power plant.

The dispute pits the internationally backed government of the West Bank against Gaza Strip's Hamas rulers.

The plant provides power to much of northern Gaza.

The European Union used to pay for the plant's fuel as part of an aid package to the Palestinian Authority.

However, the EU decided to start scaling back and said it wants the Palestinian Authority to find other ways to pay for the fuel. The Palestinian Authority demands that Hamas pay its share.

Hamas insists that the EU resume payments.

An engineer said the plant could run out of fuel as early as Thursday.
