The Haaretz daily said in its online edition that the Dor Alon company, Israel's monopoly fuel supplier to Gaza, renewed shipments to the strip after Palestinian authorities on the West Bank, still controlled by President Mahmoud Abbas' moderate Fatah movement, undertook to pay for the fuel.
The cutoff in supplies led to massive traffic disruptions in Gaza, whose 1.5 million population depends almost entirely on supplies from Israel for its survival. If extended for another day or two, it would have brought the enclave's traffic to a complete standstill.
Last week, Israel shut down its key border crossings with Gaza to prevent a possible spillover of fighting between militants of Hamas' armed wing and Fatah-allied security forces.
Israeli authorities said they would continue blocking cargo shipments to the strip to press Hamas militants into ceding power, but may organize humanitarian airlifts of food to avert a crisis in the area.
Last week's takeover of Gaza by Hamas prompted President Abbas to dissolve the national unity government his party had formed with the radical Islamists three months ago in the hope of ending an international blockade imposed on the Palestinian territories over Hamas' single-handed rule.
