The UN is warning it could be forced to suspend humanitarian aid to the Gaza Strip today because of the Israeli blockade. The United Nations Works and Relief Agency is responsible for feeding nearly two-thirds of Gaza’s 1.4 million people. Agency officials say they expect trucks to run out of fuel this afternoon. Israel has intensified military attacks and economic isolation of the Gaza Strip since Hamas took control last June. Hamas, meanwhile, says it’s awaiting an Israeli response to its latest offer of a ceasefire in the Occupied Territories.
