WASHINGTON (Reuters) - The risk of famine throughout Gaza, especially in the north, is "very high," Washington's special regional envoy for humanitarian issues said on Tuesday.

David Satterfield told reporters that Israel must do everything possible to facilitate efforts to avert a famine and called for more to be done to get aid to those in need, particularly in the north.
