Despite mounting international concern over widespread hunger in Gaza, no official famine has been declared in the territory – highlighting the complexities of determining a country's famine status.

One in three people are going without food for days, the U.N. said, as global outrage grows over Israel’s restrictions on aid to Gaza.

Some Israelis denied famine in Gaza while others protested outside the U.S. embassy on Tuesday (July 29), urging an end to starvation after a hunger monitor warned of famine and starvation related deaths in the enclave.
