More aid is supposed to be entering the Gaza Strip. Why isn’t it helping?

Under heavy U.S. pressure, Israel has promised to ramp up aid to Gaza dramatically, saying last week it would open another cargo crossing and surge more trucks than ever before into the besieged enclave.

But days later, there are few signs of those promises materializing and international officials say starvation is widespread in hard-hit northern Gaza.

Samantha Power, administrator of the U.S. Agency for International Development, said this week she accepted “credible” reports that famine is now occurring in the area and urged Israel to take further steps to expedite humanitarian aid shipments.

Power's remarks echoed those of U.S. President Joe Biden, who said on Wednesday that Israeli efforts to increase aid were “not enough.”

While Israel says it has dramatically increased the number of aid trucks entering the territory, U.N. workers report only a slight uptick — possibly because they count trucks differently.

Here’s what we know about the aid entering Gaza, and why discrepancies in reporting persist:

HOW MUCH AID IS ENTERING GAZA?

Israel says that since Sunday it has transported an average of 400 trucks a day into Gaza and that aid is now piling up on the Palestinian side of the Kerem Shalom crossing, one of two major crossings into the territory.

But Juliette Touma, communications director for the U.N. agency for Palestinian refugees, known as UNRWA, said that while aid workers have noticed a slight increase in the amount of aid entering Gaza, it’s nothing close to the surge Israel is claiming.

On Monday, UNRWA says 223 trucks of aid passed. On Tuesday, that number hit 246. On Wednesday, it was down to 141.

Meanwhile, only trickles of aid are reaching northern Gaza.
