A dire fuel shortage in the Gaza Strip has shut down all internet and phone networks. That's according to the main Palestinian provider. Thursday's outage effectively cuts off the besieged territory from the outside world. And in a signal that Israel’s ground invasion may soon expand in the south, Palestinians in parts of southern Gaza say they received evacuation notices. Most of Gaza’s 2.3 million people are crowded into the south, including hundreds of thousands who heeded Israel’s calls to evacuate the north. More than 11,400 Palestinians have been killed since the war began.
