UNITED NATIONS (Reuters) -United Nations aid chief Tom Fletcher said on Sunday that some movement restrictions appeared to have been eased by Israel in Gaza on Sunday after Israel decided to "support a one-week scale-up of aid." Fletcher said in a statement that initial reports indicate that more than 100 truckloads of aid were collected from crossings to be transported into Gaza. "This is progress, but vast amounts of aid are needed to stave off famine and a catastrophic health crisis," he said. (Reporting by Michelle Nichols; editing by Kanishka Singh)
