The Palestinian phone company says the Gaza Strip is close to losing all contact with the world because the IDF's airstrikes and ground incursion have damaged the network. Paltel Group says 90 percent of Gaza's cellular service is down, as well as many landlines, because of frequent power cuts and the inability of technicians to reach work sites. Only one of the company's back up systems is still working. The rest have been damaged in the fighting. Paltel said three technicians have been killed and several injured in the fighting.
