Gaza's only power plant will restart operation partly after a limited amount of fuel was brought in through underground tunnels, an official from the Hamas-run energy authority said Monday.

The 300,000 liters of diesel will allow the station, which stopped generating electricity last week due to a lack of fuel, to run only one of its four turbines, said the official named Ahmed Abu Al-Amrin.

The diesel was brought through a network of underground tunnels between the Gaza Strip and Egypt. "It will be pumped quickly to the station," he told Xinhua.

"This amount was brought away from official Egyptian promises to ship the fuel daily and in official ways," Abu Al-Amrin added.

Until last year, industrial diesel to the plant came from Israel, but the Israeli restrictions made the supplies irregular and insufficient. Hamas authorities then started to purchase diesel unofficially from Egypt and bring in it via underground tunnels.

On Saturday, Hamas rejected an Egyptian offer to ship diesel officially through Gaza's commercial crossing points, which are controlled by Israel.

Nearly 60 percent of power supply for the 1.6 million people in the Gaza Strip comes from the power plant and electricity directly provided by Israel and Egypt via cables.
