Gaza's power station 'hit by Israeli shelling'
Heavy shelling is continuing in Gaza, after one of its heaviest nights of bombardment in three weeks of conflict with Israel.
A fuel tank supplying the area's only power station was hit by shells, Palestinians say, with a thick column of black smoke rising from the facility.
Israel's prime minister warned of a long conflict ahead, as the country seeks to destroy Hamas targets.
